OPTICAL COMPOSITE SHEET AND DISPLAY APPARATUS COMPRISING SAME

The invention discloses an optical composite sheet and a display apparatus comprising the same. According to one realized embodiment, provided is an optical composite sheet, in which optical functional elements such as a prism sheet, a light diffusion layer and the like are combined and a light absorbing layer which selectively absorbs light of a specific wavelength band is inserted, so that optical performance and a color area can be improved than before. In particular, since the optical composite sheet satisfies a specific formula in the color transmittance in accordance with a wavelength measured for each viewing angle, the color deviation in accordance with the viewing angle can be effectively reduced. 本发明公开了一种光学复合片和包含其的显示装置。在根据实施方案的光学复合片中，结合诸如棱镜片和光扩散层的光学功能元件，并且插入选择性地吸收特定波段的光的光吸收层，因此，与现有技术相比，可以提高光学性能和色域。特别是，光学复合片的颜色透射率相对于每个视角测量的波长满足特定的关系，由此可以有效地减少相对于视角的颜色偏差。
