Problems solved by technology

[0002] The current large-size LCD (Liquid Crystal Display, liquid crystal display) panels include VA (Vertical Alignment, vertical alignment) liquid crystal panels and IPS (In-Plane Switching, in-plane switching) liquid crystal panels, etc. Compared with IPS liquid crystal panels, VA-type liquid crystal panels have more High production efficiency and low manufacturing cost have advantages, but compared with IPS liquid crystal panels, there are obvious optical property defects in optical properties, especially large-size panels require a larger viewing angle for commercial applications, and VA-type liquid crystal panels are used in The brightness of the large viewing angle is rapidly saturated with the voltage, which causes the image quality contrast and color shift of the viewing angle to deteriorate seriously compared with the image quality of the front view, resulting in the problem of color shift
[0003] In addition, the structure of the current LCD display panel is generally a laminated structure, that is, polarizers are attached above and below the liquid crystal layer. However, the thickness of a single layer of the current polarizer is about 200 μm, and the total of the upper and lower layers of polarizers requires 400 μm. thicker

Abstract

The invention relates to an optical composite film, a display panel and a display device. The optical composite film comprises a first uniaxial optical film, a second uniaxial optical film and a firstgrating film; the first uniaxial optical film comprises a platy part and multiple refraction parts formed at one side of the platy part, and multiple refraction parts are camber columns or quadrangular columns; the second uniaxial optical film is laminated at one side, close to the refraction parts, of the platy part, multiple refraction parts are held in the second uniaxial optical film, the extraordinary light refractive index of the first uniaxial optical film is greater than the ordinary light refractive index of the second uniaxial optical film; the first grating film is arranged at oneside, far away from the first uniaxial optical film, of the second uniaxial optical film. The optical composite film disclosed by the invention not only can improve the large visual angle color cast of the display panel, but also can enable the thickness of the display panel to be thinner.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical composite film layer, a display panel and a display device.
