Embodiment Construction

[0021] The technical solution of a liquid crystal display device involved in the present invention will be described in further detail below with reference to the drawings and embodiments.

[0022] Such as figure 1 As shown, this embodiment provides a liquid crystal display device, which includes: a first liquid crystal panel 10 , a second liquid crystal panel 20 and a backlight module 30 .

[0023] Such as figure 1 As shown, the first liquid crystal panel 10 is disposed on the light emitting side of the backlight module 30 . The second liquid crystal panel 20 is disposed on the surface of the first liquid crystal panel 10 away from the backlight module 30 . Wherein the first liquid crystal panel 10 and the second liquid crystal panel 20 are connected together by a transparent adhesive. The specific material used for the transparent adhesive is preferably transparent adhesive materials such as organic resin or siloxane, but it can also be other transparent adhesive material...

Abstract

The invention provides a liquid crystal display device. The liquid crystal display device comprises a backlight module, a first liquid crystal panel and a second liquid crystal panel. The second liquid crystal panel is used for a picture display panel of the liquid crystal display device. According to the invention, the deflection direction of the first liquid crystal layer is driven by the firstpixel structure layer of the first liquid crystal panel, the polarization characteristic of the light of the backlight module is further controlled, so that the second liquid crystal panel realizes anabsolute black state, the contrast ratio of the liquid crystal display device is improved, and meanwhile, the color display of the liquid crystal display device is realized by the second liquid crystal panel, so that the second substrate of the first liquid crystal panel can adopt the bare glass substrate. The production cost of the liquid crystal display device is saved to a certain extent, andthe overall thickness of the liquid crystal display device is reduced.

Description

technical field [0001] The invention relates to the technical field of plane display, in particular to a liquid crystal display device. Background technique [0002] With the continuous development of display technology, new flat-panel displays have begun to completely replace CRT displays and become mainstream display devices in the market. [0003] Flat-panel displays were initially accepted by the market as flat-panel liquid crystal displays (Liquid Crystal Display, LCD). Its lightness, thinness and other properties made it quickly accepted by the market, and then widely popularized and used, which also made its The market share is very high. However, the contrast ratio of the traditional liquid crystal display is low, which cannot meet the needs of users. Contents of the invention [0004] One aspect of the present invention is to provide a liquid crystal display device, which adopts a novel display structure, so as to realize high-contrast display. [0005] The tec...
