Liquid crystal display

Abstract

The invention discloses a liquid crystal display device, wherein, a common electrode (11) is formed in a base plate (1a) and a display electrode (12) is formed in a base plate (1b). A slit (14) is formed in the common electrode (11) at one side of the base plate (1a). The center (B) of the slit (14) is displaced from the center (B) of the display electrode facing the base plate (1b). In other words, the slit (14) canpared to the display electrode (14) looks asymmetry in the plane, so that the large perspective of the liquid crystal display device is realized, and the cost can be kept down. The invention is suitable for moving and has excellent high speed response.

Description

technical field [0001] The present invention relates to a liquid crystal display device capable of wide viewing angle, high-speed response, and bright display. Background technique [0002] In recent years, liquid crystal displays (LCDs (Liquid Crystal Displays)) have been widely used in display units of personal computers, car navigation systems, digital cameras, digital video cameras, mobile phones, liquid crystal televisions, portable information terminals, and the like. However, LCDs have a narrower field of view than conventional CRTs (Cathode-RayTube), requiring improvements in viewing angle characteristics. [0003] As a means of widening the viewing angle, for example, it is disclosed that an opening pattern (slit) is formed in a display region of a pair of facing electrodes of a TN type liquid crystal display device (Patent Document 1). The slits are formed such that their longitudinal directions are perpendicular to the initial (when no voltage is applied) alignme...

Problems solved by technology

[0007] However, in the above-mentioned improved TN mode, although the viewing angle characteristics can be improved accordingly, sufficient viewing angle cannot be obtained yet.

In addition, in the electric field response in which the liquid crystal molecules are guided, the influence of backflow is large, so high-speed response cannot be achieved, and there is also the problem of sacrificing the brightness of the front side.

[0008] In addition, in the MVA mode, in order to provide protrusion-shaped structures on the substrate surface, the manufacturing process becomes complicated, which is a major cause of cost increase.

Furthermore, in order to eliminate grayscale inversion, it is necessary to reduce the transmittance of white display, so if high luminance is to be achieved, power consumption will increase

In addition, like the TN method, the impact of back flow is large, and the high-speed response is limited.
