- the humidification environment formed in the pasting part 100 of Example 1 is shown in the items of “room temperature and humidity” and “influence by humidification” of Example 1 listed in the table of FIG. Specifically, after the polarizing film corresponding to the optical functional film 1 or the optical functional film 1 ′ is attached to both surfaces of the liquid crystal cell corresponding to the panel member 5, the liquid crystal alignment unevenness (due to static electricity) is brought into contact with the liquid crystal cell terminal.

- FIG. 7 is a schematic diagram of a pasting unit 100 that constitutes a part of a normal RTP pasting device 10 or a sheet-type pasting device 10 ′ configured to correspond to Comparative Example 1.
- the affixing unit 100 according to the comparative example 1 is provided with the same air filtering means 120 (BV-RTH1L, manufactured by Panasonic) as the top plate 103, but the affixing unit 100 includes an inner portion of the affixing unit 100.
- the spraying means 110 including the spray mechanism 113 as in the first embodiment is not provided.
- the humidification environment of the pasting part 100 according to the comparative example 1 is a room temperature of 22 ° C. and a relative humidity of 43% RH. As compared with Example 1, naturally, wetting does not occur inside the sticking part 100 according to Comparative Example 1. However, charge attenuation (static elimination) of the liquid crystal alignment unevenness is required up to 134 seconds, which is three times or more that in the first embodiment. This is not a value that can be adopted in the manufacturing process of continuously manufacturing the optical display device 6.
- the top plate 103 is provided with the same air filtering means 120 (BV-RTH1L, manufactured by Panasonic Corporation) as in Example 1, and the affixing portion 100 is similar to Example 1, A spraying means 110 including a spray mechanism 113 is provided inside the sticking unit 100.
- a difference from Example 1 is that a commercially available sprayer (round mist KSAMF manufactured by Everloy) equipped with a two-fluid nozzle is used in the sprayer 1130.
- the two-fluid nozzle which is a type of fluid nozzle that blows out a fluid that deforms with a slight force, such as liquid or gas, under pressure, and blows out compressed air and water together. Used to make fine water droplets, that is, to spray.
- the above-mentioned commercially available fine water droplet spray nozzle (AKI MIST-E03C manufactured by Ikeuchi Co., Ltd.) is a kind of two-fluid nozzle, but this is equipped with a special mechanism to generate fine water droplets from the usual two-fluid nozzle. It has been done.
- the two-fluid nozzle of the nebulizer 1130 used in Comparative Example 2 is the one shown in the table of FIG. 11 and having a spray amount set to 3.1 L / min (Everloy Round Mist KSAMF). Is done. This is a spray condition in which the spray amount is 70 times or more as compared with the spray condition of Example 1. Therefore, as shown in the item “Effects of humidification” in FIG. 10, the pasting part 100 according to the comparative example 2 was wetted immediately after spraying, and the experiment was impossible.
- the charge decay (static elimination) of the liquid crystal alignment unevenness is 42 seconds, which is not a problem value in the manufacturing process for continuously manufacturing the optical display device.
- wetting does not occur at the same time. However, it has been confirmed that wetting has occurred inside the affixing part 100 after a long period of use of, for example, one day.
- the humidification environment that can be employed in the continuous manufacturing process of the optical display device 6 should be less than 60% RH.
- the inspection process after the pasting process in the state where the liquid crystal alignment unevenness has occurred, it is confirmed that the inspection of the panel member 5 is hindered and the problem that the continuous production of the panel member 5 is hindered is likely to occur. It was done.
- the relative humidity at room temperature 22 ° C. is higher than 75% RH, wetting occurs in the affixing portion 100 simultaneously or in a short time, so that the manufacturing apparatus 10 or the manufacturing apparatus 10 ′ deteriorates, the panel member 5 or the optical functional film. 1 or a problem occurs in the quality of the optical functional film 1 '. Therefore, it is preferable to control the relative humidity at room temperature of 22 ° C. to 60 to 75% RH.
- the performance of the spray mechanism 113 and the spray conditions greatly affect the humidification environment of the pasting part 100 that enables sufficient static elimination while preventing the occurrence of wetting.
- the fine water droplets 20 to be sprayed preferably have an average particle size of 10 ⁇ m or less. For example, when the maximum particle size is larger than 50 ⁇ m, not only the wetting inside the sticking part 100 is likely to occur, but also the filtration mechanism 113 combined with the filtration membrane causes clogging of the filtration membrane. It becomes a factor.
- the spray conditions are 0.04 L / min.
- the spraying process is omitted. Therefore, according to the comparative example 1, wetting does not occur inside the sticking part 100, but it cannot be neutralized within an appropriate time such as 134 seconds for neutralization. Then what happens in the case of Comparative Example 2 in which the spraying condition is set to 3.1 L / min?
- the top plate 103 is provided with the same air filtering means 120 (BV-RTH1L made by Panasonic) as the pasting portion 100 of Comparative Example 2, Immediately after spraying by the sprayer 1130 constituting the spray mechanism 113, wetting occurred inside the sticking unit 100. Therefore, experiment is impossible. Naturally, this is a spraying condition that cannot be employed in the manufacturing process for continuously manufacturing the optical display device 6.
- the spraying condition when the spraying condition is less than 0.02 L / min, it is not possible to form a sufficiently humidified environment, and as a result, the charge cannot be sufficiently removed.
- the spraying condition is larger than 0.05 L / min, even if it passes through a filter membrane, the filter membrane is clogged and an appropriate humidified environment cannot be formed.
- the spraying condition with the minute water droplets 20 having an average particle diameter of 10 ⁇ m or less is 0.02 to 0.05 L / min.
