Embodiment Construction

[0024] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0025] see figure 1 and figure 2 , the present invention provides a polarizer, including a polarizing layer 10 . The polarizing layer 10 includes a plurality of polarizing units 11 sequentially arranged on the same plane. Among the plurality of polarizing units 11, at least two polarizing units 11 have different polarization directions. After the light is polarized through the polarizing units 11 with different polarization directions, the polarization directions of the emitted polarized light are different. Therefore, the light passes through the polarizer of the present invention. After the polarization treatment is performed, polarized light in at least two polarization directions can be emitted.

[0026] Preferably, see figure 2 , am...

Abstract

The invention provides a polaroid and a liquid crystal display device. The polaroid includes a polarizing layer including a plurality of polarizing units arranged in sequence on the same plane. Amongthe plurality of polarizing units, at least two polarizing units have different polarization directions, so that light is polarized through the polaroid and then emits polarized light with at least two kinds of polarization directions. Therefore, a problem of the eyestrain caused by the single polarization direction of the emitted light and a problem of a large view-angle colour cast of the liquidcrystal display device are solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a polarizer and a liquid crystal display device. Background technique [0002] In the field of display technology, flat panel display devices such as liquid crystal display devices (Liquid Crystal Display, LCD) have gradually replaced cathode ray tube (Cathode Ray Tube, CRT) display devices. The liquid crystal display device has many advantages such as a thin body, power saving, and no radiation, and has been widely used. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Generally, a liquid crystal display panel consists of a color filter (ColorFilter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) array substrate, a liquid crystal (Liquid Crystal, LC) and a sealant frame sandwiched between the color filter substrate and...
