Abstract

The invention discloses a reflective polaroid and a liquid crystal display device, relates to the technical field of display, and aims at solving a technical problem that the utilization rate of backlight provided by a backlight source is low because a polaroid absorbs intercepted polarized light. The reflective polaroid comprises one or more reflective polarization layers, and each reflective polarization layer comprises a plurality of reflecting rods which are parallel to each other in a length direction and arranged at intervals. When the number of the reflective polarization layers is greater than one, the reflective polarization layers are arranged in a stacked manner, and interlayer gaps are respectively formed between each reflective polarization layer and the adjacent reflective polarization layers. The length directions of the reflecting rods of two adjacent reflective polarization layers are not perpendicular. The backlight provided by the backlight source is reflected for many times, and then is reflected diffusely to form polarized light, wherein the polarization direction of the polarized light is parallel to the length direction of the reflecting rod of the reflective polarization layer of the reflective polaroid or the last reflective polarization layer. The reflective polaroid does not absorb the intercepted polarized light, thereby improving the utilization rate of the light provided by the backlight source.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a reflective polarizer and a liquid crystal display device. Background technique [0002] At present, the main structure of a liquid crystal display device includes a liquid crystal display panel and a backlight that provides backlight for the liquid crystal display panel. The basic principle of its display screen is: the backlight provides backlight for the liquid crystal display panel, and then the backlight passes through The polarizer between the panels generates polarized light with a specific polarization direction. Then, the polarized light with a specific polarization direction enters the liquid crystal layer in the liquid crystal display panel. With the arrangement and twist of the liquid crystal molecules in the liquid crystal layer, the liquid crystal display panel A picture with bright and dark changes on the screen, thus showing a rich picture. [0003] However, co...
