Liquid crystal display with inconstant inter-electrode distances and transverse electric fields

Abstract

The invention provides a liquid crystal display with transverse electric fields. The liquid crystal display comprises a first substrate, a second substrate and a liquid crystal layer. A plurality of first electrodes and at least one second electrode are formed on the first substrate, and the liquid crystal layer is sandwiched between the two substrates. Each first electrode comprises a column of electrode sections, and the minimum distance from each first electrode to the corresponding adjacent second electrode is smaller than the maximum distance from the first electrode to the second electrode. Each second electrode is a strip-shaped electrode or comprises a column of electrode sections. Electrodes of each column of electrode sections of the corresponding first electrode or the corresponding second electrode are V-shaped electrodes, each V-shaped electrode rotates by a specific angle, or each of the electrodes of each column of electrode sections of the corresponding first electrode or the corresponding second electrode comprises at least one protrusion and at least one sunken portion. Each column of electrode sections also can be an electrode in the shape of a sinusoidal wave. The orientations of the first electrodes and the second electrodes are parallel to data cables in the liquid crystal display, or a specific angle is formed between each data cable and the orientation of the corresponding first electrode or the corresponding second electrode.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to an electrode structure of a transverse electric field type liquid crystal display. Background technique [0002] One characteristic of liquid crystal molecules is that they have different optical rotations or different refraction effects when they are arranged differently. Liquid crystal displays use this characteristic to control the light transmittance to produce images. Due to the structure of liquid crystal molecules and the influence of optical characteristics, the twisted nematic liquid crystal display has good light transmittance, but the viewing angle of the display is very narrow. [0003] In order to solve the problems of light transmittance and viewing angle, the twisted vertical alignment mode is used to improve the transmittance and increase the viewing angle. Since the liquid crystal molecules are vertically aligned, when the liquid crystal molecules receive a lower vol...

Problems solved by technology

[0005] In a traditional in-plane switching liquid crystal display, the two electrodes formed on the same substrate are usually parallel to each other, so the threshold voltage for driving this type of in-plane switching liquid crystal display is relatively high, and the contrast of the display is also poor.
