Pixel structure, active component array substrate and liquid crystal display (LCD) panel

Abstract

The invention relates to a pixel structure which is arranged on a substrate, wherein the substrate has a horizontal direction and a vertical direction and the pixel structure can be driven by a scan line and a data line. The pixel structure comprises a pixel electrode and an active component, wherein the pixel electrode is provided with a first extension part and a second extension part which is connected to the first extension part; and the first extension part forms a first included angle of theta degrees together with the horizontal direction, the second extension part forms a second included angle of 360-theta degrees together with the horizontal direction, and the data line is in parallel with the first extension part and the second extension part. The pixel electrode is also provided with multiple slits which are vertical to the data line, and the pixel electrode is electrically connected with the scan line and the data line through the active component. By utilizing the way provided by the invention, the pixel electrode (the first extension part and the second extension part) can be formed on the tilted direction of liquid crystal molecules, so that the liquid crystal molecules can be driven to an accurately backward direction. Therefore, the pixel structure provided by the invention has the advantages of good liquid crystal efficiency, penetration rate, contrast value and liquid crystal response time.

Description

technical field [0001] The present invention relates to a pixel structure, an active component array substrate having the pixel structure, and a liquid crystal display panel, especially a pixel structure capable of improving liquid crystal efficiency (Liquid crystal efficiency), and an active component array substrate having the pixel structure and LCD panel. Background technique [0002] At present, liquid crystal display panels generally use vertical alignment (Vertical Alignment, VA) technology to make liquid crystal molecules fall in a specific direction, so as to achieve a wide viewing angle requirement. Regarding the vertical alignment technology of the liquid crystal display panel, there are mainly Multi-domain Vertical Alignment (MVA) and Pattern Vertical Alignment (PVA). [0003] figure 1 It is a schematic cross-sectional view of a multi-domain vertical alignment liquid crystal display panel in the prior art. Please refer to figure 1 , the multi-domain vertical ...

[0006] However, setting a large number of slits S and protrusions P will increase the number of dark lines in the opening area of ​​the pixel structure, resulting in a decrease in transmittance

In addition, the liquid crystal molecules 132 near the protrusion P of the multi-domain vertical alignment type liquid crystal display panel 100 have a pretilt angle, which will cause light leakage in the dark state and decrease in contrast value.
