Liquid crystal display device

Abstract

The invention discloses a liquid crystal display device which comprises at least one of pixel regions, wherein each pixel region comprises a first base plate, a second base plate and a liquid crystal layer. The surface of the first base plate is provided with a first electrode layer. The first electrode layer comprises a plurality of main slits, a plurality of central thin slits and a plurality of edge thin slits. The central thin slits and the edge thin slits are respectively positioned at the centers and the edges of the pixel regions. The ratio of the width of each edge thin slit to the width of every two adjoining edge thin slits at the first electrode layer is lager than the ratio of the width of each central thin slit to the width of every two central thin slits at the first electrode layer. The surface of the second base plate is provided with a second electrode layer. The liquid crystal layer is arranged between the first electrode layer and the second electrode layer. The invention can improve the phenomenon of the dark fringe at the edges of the pixel region of the liquid crystal display device to increase the transmissivity of the pixel regions.

Description

technical field [0001] The present invention relates to a display device, and more particularly, to a liquid crystal display device. Background technique [0002] For the rapid progress of the multimedia society, most of them benefit from the rapid progress of semiconductor devices or display devices. As for display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation has gradually become the mainstream of the market. [0003] At present, the performance requirements of the market for liquid crystal display devices are toward high contrast ratio, no gray scale inversion, low color shift, high luminance, and high color richness. brightness, high color saturation, fast response, and wide viewing angles. At present, the technologies that can meet the requirements of wide viewing angle include twisted nematic (TN) liquid crystal plus wi...

Problems solved by technology

Depend on figure 2 It can be found that the edge of the pixel area and the area R10 in the corner are prone to dark lines when displaying the picture

As a result, the transmittance of the known multi-domain vertical alignment liquid crystal display device will be greatly reduced, and its display quality will be affected
