摘要:
Disclosed is a complex film for a display apparatus, which comprises a base film; an anti-reflection film formed on a first surface of the base film and adapted to prevent reflection of external light; an external light shielding film formed on a second surface opposite to the first surface and including an external light shielding pattern, the external light shielding pattern having a plurality of external light shielding parts formed on a surface of the external light shielding film; and an adhesive film formed on the external light shielding film and including at least one colorant having a selective wavelength absorption capability. The complex film has multi-functionalities such as electromagnetic wave shielding, external light absorption, near infrared ray shielding, color correction, and the like, thereby simplifying an assembly process of the display apparatus, and reducing the thickness of the display apparatus.

An optical sheet and a display optical filter which can increase a contrast ratio in a bright room are provided. The optical sheet for the display optical filter includes a transparent substrate including a plurality of pattern grooves formed thereon; and a light shielding pattern formed of a light absorbent material filled in the plurality of pattern grooves. The light shielding pattern may be formed of a material for either absorbing or shielding light filled in the plurality of pattern grooves. In particular, when an external illuminance increases from 0 Lux to 250 Lux, a reduction rate of a color gamut in CIE color coordinates may be 9% or less with respect to NTSC, and the reduction rate of the color gamut is relatively less in comparison with the case where the optical sheet of the present invention is not used.

An optical filter for compensating for color shift is provided in front of a display panel of a display device. The optical filter includes a background layer and a green wavelength absorption pattern provided with a predetermined thickness on the background layer. The green wavelength absorption pattern absorbs a green wavelength of light. The green wavelength absorption pattern contains a material that absorbs a green wavelength of light in the range of 510 nm to 560 nm, and can also contain a white light absorbing material. A green's complementary color absorbing part absorbs a wavelength of light complementary to green, and contains at least one of a material absorbing a blue wavelength of light in the range of 440 nm to 480 nm and a material absorbing a red wavelength of light in the range of 600 nm to 650 nm.
