Abstract

The disclosure proposes an optical film, which includes a substrate, a medium layer, a plurality of first oblique sheets, and a plurality of second oblique sheets. The dielectric layer is located on the substrate. The first oblique sheets are arranged in the medium layer and arranged along the first direction, and the first oblique sheets and the substrate have a first angle. The second oblique sheets are arranged in the medium layer and arranged along the first direction, and the second oblique sheets and the first oblique sheets have a second angle.

Description

technical field [0001] The present disclosure relates to an optical film. Background technique [0002] Generally speaking, for a display device using the liquid crystal display principle, due to the characteristics of the liquid crystal layer and the polarizing layer in the display device, when viewing the display device from different viewing angles, it may be found that the color contrast, light intensity, etc. are not uniform. That is to say, the optical characteristics of the liquid crystal display device will change with the viewing angle of the viewer. [0003] In order to improve the above problems, an optical compensation film (compensation film) is usually added on the polarizing layer to adjust the optical characteristics of different viewing angles. However, due to the limitation of the material selection and process of the polarizing layer and the optical compensation film, the above solutions cannot solve the problem of dark state light leakage at certain spec...
