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 layer, a display panel and a display device. An optical composite film layer includes a first single optical axis optical film layer, a second single optical axis optical film layer and a first grating film layer, and the first single optical axis optical film layer includes a plate-shaped portion and a plate formed on the plate-shaped portion A plurality of refraction parts on one side, the plurality of refraction parts are curved columns or quadrangular prisms; the second single optical axis optical film layer is laminated on the side of the plate-shaped part close to the refraction parts, and the plurality of refraction parts are accommodated in the second In the single optical axis optical film layer, the extraordinary light refractive index of the first single optical axis optical film layer is greater than the ordinary light refractive index of the second single optical axis optical film layer; the first grating film layer is arranged on the second single optical axis optical film layer. The film layer is on the side away from the first single optical axis optical film layer. The above-mentioned optical composite film layer can not only improve the large viewing angle deflection of the display panel, but also make the thickness of the display panel 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.
