Abstract

The invention discloses a liquid crystal display device which comprises a display panel and a light modulator. The light modulator is arranged on one side of the display panel. The light modulator comprises a third base plate, a fourth base plate and a second liquid crystal layer arranged between the third base plate and the fourth base plate. The third base plate comprises a third substrate, a lower common electrode and a pixel electrode, wherein the lower common electrode and the pixel electrode are arranged in an insulated and spaced mode, the lower common electrode is divided into a plurality of sub lower common electrodes, and the pixel electrode is divided into a plurality of sub pixel electrodes; and the fourth base plate comprises a fourth substrate and an upper common electrode, wherein the upper common electrode is arranged on the fourth substrate body. In the liquid crystal display device, the lower common electrode and the pixel electrode are divided into a plurality of blocks, or the upper common electrode and the pixel electrode are divided into a plurality of blocks, so that pressure difference region control between the pixel electrode and the upper common electrodeof the liquid crystal display device can be realized, and regional control of wide and narrow viewing angle display is realized.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device. Background technique [0002] Liquid crystal display devices have the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and they occupy a dominant position in the field of flat panel display. [0003] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been expanded from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy. In order to avoid commercial loss or embarrassment caused by leakage of screen information. Therefore, in addition to the wide viewing angle, the display device is also required to have the function of switching between the wi...
