Vertical alignment type liquid crystal display (LCD) with step width smaller than 2.5 mm

Abstract

The invention discloses a vertical alignment type liquid crystal display (LCD) with the step width smaller than 2.5 mm. The vertical alignment type LCD comprises ITO layers distributed on upper glass and lower glass in a box body and ITO layers distributed on an upper step or a lower step or the upper step and the lower step outside the box body, wherein the ITO layers on the steps are regularly spaced in a hollow-out mode after exposure and acid embossing, the steps at the hollow-out positions are provided with ITO filling blocks, and each ITO filling block is divided into two portions by a gap in the width direction of the corresponding step. The gaps are in linear or folded shapes, and the gap width ranges from 0.075 mm to 0.10 mm. Separation distances are reserved between the ITO filling blocks and the ITO layers adjacent to the ITO filling blocks, and a minimum value of each separation distance is 0.05 mm. The step width is smaller than 2.5 mm. The frictional oriented stripes caused when electrodes on the steps are parallel to the friction direction, the vertical alignment type LCD is simple to manufacture, and the frictional stripe avoiding effect is good.

Description

(1) Technical field: [0001] The invention relates to a display device, specifically a vertical alignment type LCD liquid crystal display with a step width less than 2.5 (mm). (two) background technology: [0002] Vertical Alignment (VA) liquid crystal displays are more and more widely used in LCD displays in recent years. [0003] Since the liquid crystal molecules are approximately vertically aligned during its operation, the rubbing direction is required to be parallel to the direction of the normal viewing angle. Therefore, for those displays whose steps are located on the upper or lower steps or the upper and lower steps of the front viewing direction, the ITO layer on the conventional steps has a relatively regular Hollowed out at regular intervals, there is unevenness, and after friction orientation, it is easy to cause directional memory stripes in the box. [0004] How to avoid friction stripes from structural design or process has become a problem to be solved by V...
