Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below with examples in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the liquid crystal display provided in this embodiment includes a liquid crystal panel 100 and a backlight module 200, the liquid crystal panel 100 is arranged opposite to the backlight module 200, and the backlight module 200 provides a display light source to the liquid crystal panel 100, so that the liquid crystal panel 100 displays image.

[0023] Among them, such as figure 2 As shown, the liquid crystal panel 100 includes a thin film transistor (TFT) substrate 10 and a color filter (CF) substrate 20 disposed opposite to each other, and a liquid crystal layer 30 located between the TFT substrate 10 and the color filter substrate 20 . In this embodiment, the liquid crystal layer 30 adopts a vertical alignment (Vertical A...

Abstract

The invention discloses a polaroid. The polaroid comprises a first protective film, a polarizing film and a second protective film which are laminated, wherein the second protective film is further sequentially provided with a coarse structural layer and a surface protective film. The invention further discloses a liquid crystal panel which comprises a thin film transistor substrate and a colorful optical filter substrate oppositely arranged as well as a liquid crystal layer which is arranged between the thin film transistor substrate and the colorful optical filter substrate. The thin film transistor substrate is connected with a first polaroid and the colorful optical filter substrate is connected with a second polaroid. The second polaroid is the polaroid disclosed by the invention. Furthermore, the invention further discloses a liquid crystal display which comprises the liquid crystal panel.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a polarizer, a liquid crystal panel and a liquid crystal display. Background technique [0002] Liquid Crystal Display (LCD) is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, and is placed in front of a light source or a reflective surface. Liquid crystal displays have low power consumption, high image quality, small size, and light weight, so they are favored by everyone and become the mainstream of displays. Currently, liquid crystal displays are mainly thin film transistor (Thin Film Transistor, TFT) liquid crystal displays. [0003] As the area of ​​the TFT-LCD becomes larger and larger, its viewing angle increases continuously, the contrast of the picture decreases continuously, and the definition of the picture decreases. For vertical alignment (Vertical Alignment, VA) mode liquid crystal panels,...
