Abstract

A liquid crystal display (LCD) display device comprises a first substrate, a second substrate and a liquid crystal molecular layer, wherein the first substrate and the second substrate are oppositely arranged. The liquid crystal molecular layer is arranged between the first substrate and the second substrate. The first substrate comprises a first shared electrode which is arranged on the inner side, relative to the second substrate, of the first substrate. The second substrate comprises a plurality of scanning lines and a plurality of data lines, and the scanning lines and the data lines are arranged on the inner side, relative to the first substrate, of the second substrate, and the scanning lines intersect with the data lines in an insulating mode. The scanning lines and the data lines define a plurality of subpixel areas. Each subpixel area comprises a switch element and a subpixel electrode. The switch element is electrically connected with the scanning lines, the data lines and the subpixel electrodes. When the first shared electrode and the subpixel electrodes obtain a driving signal, a tilted electric field for driving liquid crystal molecules to pretilt is formed between the first shared electrode and the subpixel electrodes. The LCD device is capable of reducing manufacturing cost, simplifying manufacturing process and improving product performance.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device with a wide viewing angle. Background technique [0002] Liquid crystal display devices are widely used in handheld information exchange terminals and various display fields because of their low space occupation rate and low energy consumption. The liquid crystal display device controls the alignment direction of liquid crystal molecules when the light from the light source passes through the liquid crystal layer through an electric field, and changes the transmittance to display images. According to different specific principles, the liquid crystal display device has developed from the early TN mode to the current vertical alignment (VA) mode and in-plane switching (In-Plane Switching, IPS) mode. [0003] Vertically Aligned (VA) mode is a wide viewing angle technology for liquid crystal display devices. Specifically, a liquid crystal display...
