- ELD electroluminescent display
- LCD displays are currently expanding their range of use, including notebooks, personal computer monitors, LCD TVs, automobiles, and airplanes, accounting for about 80% of the flat panel market, and are booming to date due to a sharp increase in LCD demand worldwide.
- the optical film used in such a liquid crystal display does not necessarily have high utilization efficiency of light emitted from the backlight. This is because 50% or more of the light emitted from the backlight is absorbed by the back side optical film (absorption type polarizing film).
- a reflective polarizer is provided between the optical cavity and the liquid crystal assembly.
- a second object of the present invention is to provide a reflective polarizer which can be integrally formed without forming a separate adhesive layer between the core layer and the skin layer.
- the first polarization may be longitudinal, and the second polarization may be transverse.
- the skin layer is formed on at least one surface of the core layer in the molten state, it does not go through a separate bonding step. This not only significantly reduces the manufacturing cost but is also very advantageous in maximizing optical properties at a limited thickness.

- a birefringent interface may be formed between the plate-like polymer (first component) and the substrate (second component) forming the core layer.
- the magnitude of the substantial coincidence or mismatch of the refractive indices along the X, Y, and Z axes in the space between the substrate and the plate-shaped polymer is the degree of scattering of the light polarized along the axis. Affects.
- the scattering power varies in proportion to the square of the refractive index mismatch.
- the degree of mismatch in refractive index along a particular axis the more strongly scattered light polarized along that axis.
- the first polarized light (P wave) is transmitted without being affected by the birefringent interface formed at the boundary between the substrate and the polymer, while the second polarized light (S wave) is transmitted at the birefringent interface formed at the boundary between the substrate and the polymer. Under the influence of this, modulation of light occurs. Through this, the P wave is transmitted, and the S wave generates light modulation such as scattering and reflection of light, and thus, polarization is separated.
- the first component, the second component and the skin layer component are respectively supplied to the extruded parts.
- the first component may be used without limitation as long as the polymer is dispersed in the second component forming the substrate and used in a reflective polarizer in which a conventional polymer is dispersed.
- the first component, the second component and the skin layer component can be supplied separately to the independent extrusion parts, in this case, the extrusion part may be composed of three or more.
- the extrusion part may be composed of three or more.
- the extruder may be an extruder, which may further include heating means or the like to convert the supplied polymers into a liquid phase.
- the skin layer component transferred from the extruded part is laminated on at least one surface of the core layer (sea-island composites).
- the skin layer component may be laminated on both surfaces of the core layer.
- the material and the thickness of the skin layer may be the same or different from each other.
- step (3) can be omitted.
- it may further include the step of stretching the reflective polarizer, and more specifically (5) cooling the polarizer induced the spread induced in the flow control unit And smoothing; (6) stretching the polarizers subjected to the smoothing; And (7) heat setting the stretched polarizer.
- the first extrusion part 220 to which the first component is injected the second extrusion part 221 to which the second component is injected, and the third extrusion part 222 to which the skin layer component is injected are included.
- the first extrusion part 220 communicates with the spin block part C including the island-in-the-sea extrusion mold 223 and supplies the first component in a molten state.
- the second extrusion part 221 also communicates with the spin block part C and supplies the second component in a molten state to the island-in-the-sea extrusion mold 223 included therein.
- the island-in-the-sea type extrusion mold 223 produces the island-in-the-sea composites in which the first component is dispersed in the second component.

Therefore, the third extrusion part 222 and the feed block portion 224 may be in communication with each other.
