Abstract

The invention discloses a liquid crystal display device and a liquid crystal display device manufacturing method. The liquid crystal display device comprises an array substrate, a color film substrateand a liquid crystal layer, wherein a plurality of first pixel units and a plurality of second pixel units are formed on the array substrate, the array substrate comprises a shielding layer, and theshielding layer is arranged in an region corresponding to the second pixel units and used for shielding front viewing angle light leakage during full-narrow viewing angle display of the liquid crystaldisplay device; the color film substrate comprises a third conducting layer, and the third conducting layer is a visual angle control electrode. According to the liquid crystal display device manufactured by means of the liquid crystal display device manufacturing method, wide viewing-angle display, full-narrow viewing-angle display and left-right narrow-viewing-angle display can be achieved, left-right peep prevention and up-down peep prevention can be achieved simultaneously in a full-narrow viewing-angle mode, and the peep prevention effect is greatly improved; the shielding layer can shield part of light leakage at a front viewing angle, and can prevent light leakage at the front viewing angle in a full-narrow viewing angle mode, so that large-viewing-angle light leakage is achieved,the front-viewing-angle light leakage is avoided or reduced and the display effect is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device and a method for manufacturing the 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 costs, and occupy a dominant position in the field of flat panel displays. 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 req...
