The frame layer 25 is disposed at a predetermined interval from the light shielding layer 24, and the seal member 40 is disposed between the frame layer 25 and the light shielding layer 24. The frame layer 25 has a width of about several millimeters to several tens of millimeters. Although the frame layer 25 may be formed with the same width on all four sides, in this embodiment, as shown in FIG. 1, a logo is formed on one side in the longitudinal direction of the CF substrate 20 (A direction side). Since the portion 25b (logo / pattern forming portion) is provided, one side of the frame layer 25 on the A direction side is formed with a large width.

As shown in FIG. 3, the frame layer 25 includes a frame forming portion 25a representing a frame pattern and a logo forming portion 25b representing a mark (characters, figures, symbols, etc.). In the present embodiment, the frame forming portion 25a is formed of the same material (resin) as the BM layer 22 and the light shielding layer 24, and is formed simultaneously in the same manufacturing process as the BM layer 22 and the light shielding layer 24. In other words, the frame forming portion 25a is simultaneously formed using a common mask designed for the BM layer 22, the light shielding layer 24, and the frame forming portion 25a. For this reason, the frame forming portion 25 a is formed to have substantially the same thickness as the BM layer 22 and the light shielding layer 24. The frame forming portion 25a may be formed so as to be connected to the light shielding layer 24 as shown in FIG. In this case, the seal member 40 is bonded to the insulating substrate 21 through the frame forming portion 25a.

The logo forming portion 25b (see FIG. 3) is formed of the same material (resin) as the red layer 23R, the green layer 23G, or the blue layer 23B of the color filter layer 23, and the red layer 23R, the green layer 23G, or the blue layer 23B They are formed simultaneously in the same manufacturing process. That is, the logo forming portion 25b is simultaneously formed using a common mask designed for the red layer 23R, the green layer 23G or the blue layer 23B and the logo forming portion 25b. For this reason, the logo formation part 25b is formed in the same thickness as the red layer 23R, the green layer 23G, or the blue layer 23B.

In addition, you may form the logo formation part 25b with a metal material. Examples of the metal material include titanium, aluminum, tungsten, and molybdenum used for the gate electrode (not shown) of the TFT element of the TFT substrate 10.

Moreover, it can suppress that the thickness of the display panel 1 becomes large.

As described above, the frame layer 25 is formed of the same material and the same thickness as the BM layer 22 and the color filter layer 23 formed in the display region 20a. As a result, the frame layer 25 can be formed simultaneously using the same mask in the same manufacturing process as the BM layer 22 and the color filter layer 23. Moreover, since the BM layer 22 and the color filter layer 23 are small in thickness, the thickness of the frame layer 25 can be reduced.

Also, as described above, by forming the frame forming portion 25a from the same material as that of the BM layer 22, the frame pattern can be made to be a commonly used black.

Further, as described above, the frame forming portion 25a and the logo forming portion 25b are different from each other by forming the frame forming portion 25a with the BM layer 22 and forming the logo forming portion 25b with the color filter layer 23 or a metal material. Can be formed into color. Thereby, the logo formation part 25b can be made easy to see. That is, the visibility of the mark can be improved.

Further, as described above, if the seal member 40 is disposed between the frame layer 25 and the light shielding layer 24, the seal member 40 can be bonded to the insulating substrate 21 of the CF substrate 20 without the frame layer 25 interposed therebetween. . Thereby, it can suppress that the adhesive strength of the sealing member 40 falls.

Further, as described above, if the CF substrate 20 is formed using a tempered glass substrate, the display panel 1 can be prevented from being damaged by an external force.

Further, as described above, if the CF substrate 20 is formed using a resin substrate, the display panel 1 can be reduced in weight. Further, if the TFT substrate 10 is also formed using a resin substrate, the display panel 1 can be configured to be bendable.

That is, the logo forming part 125b may be formed with the same material (resin) as the BM layer 22 and the light shielding layer 24 and with the same thickness. Moreover, the logo formation part 125b may be simultaneously formed in the same manufacturing process as the red layer 23R, the green layer 23G, or the blue layer 23B of the color filter layer 23, as shown in FIG. That is, the logo forming portion 125b may be formed with the same thickness (the same material and resin) as the red layer 23R, the green layer 23G, or the blue layer 23B of the color filter layer 23. In this case, the frame forming portion 125a and the logo forming portion 125b are formed of the same material as two different layers of the red layer 23R, the green layer 23G, and the blue layer 23B, respectively.

Other structures of the second embodiment are the same as those of the first embodiment.

In the present embodiment, as described above, by forming the frame forming portion 125a from the same material as the color filter layer 23, the frame pattern can be colored, and the design can be improved.

Other effects of the second embodiment are the same as those of the first embodiment.

(Third embodiment)
In the third embodiment, as shown in FIG. 9, unlike the first and second embodiments, the frame forming portion 225a of the frame layer 225 is formed of a metal material. Examples of the metal material include titanium, aluminum, tungsten, and molybdenum used for the gate electrode (not shown) of the TFT element of the TFT substrate 10.

Other structures of the third embodiment are the same as those of the first and second embodiments.

Other effects of the third embodiment are the same as those of the first and second embodiments.

(Fourth embodiment)
In the fourth embodiment, the case where the CF substrate 20 protrudes toward the A direction with respect to the TFT substrate 10 will be described with reference to FIGS. 10 and 11 unlike the first to third embodiments.
