Abstract

The invention provides a liquid crystal display device, and the device comprises a liquid crystal layer which is divided into a plurality of pixels and is provided with a plurality of electrodes which apply voltages to the liquid crystal layer. Each pixel comprises a first subpixel and a second subpixel. When each pixel displays a gray scale gk, the voltages applied to the liquid crystal layer at each pixel at the first subpixel and the second subpixel are V1(gk) and V2(gk). Supposing that delta(V12(gk))=V1(gk)-V2(gk), delta(V12(gk)) is greater than zero and meets a relation: delta(V12(gk))>delta(V12(gk+1)) when the displayed gray scale gk is less than a preset gray scale gs; delta(V12(gk)) is greater than zero and meets a relation: delta(V12(gk))<delta(V12(gk+1)) when the displayed gray scale gk is not less than the preset gray scale gs, wherein gk is not less than zero and not greater than n, gk and n are integers greater than zero, and n represents the gray scale of the highest brightness.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a technology for improving the gamma characteristics of the liquid crystal display device at different viewing angles. Background technique [0002] Liquid crystal display devices are flat-panel display devices that have advantages such as high resolution, thin shape, light weight, and low power consumption. In recent years, with the improvement of display performance, improvement of production capacity, and improvement of price competitiveness with other display devices , the market scale is expanding rapidly. [0003] In the conventional liquid crystal display device of general twisted nematic mode (TN mode), the major axes of the liquid crystal molecules having positive dielectric constant anisotropy can be aligned approximately parallel to the substrate surface, and the alignment treatment is performed to make the liquid crystal molecules The long axis of the liquid crystal...
