Abstract

The invention discloses a pixel structure, which is suitable for being controlled by a scanning line and a data line of a film transistor array base plate of a multiple field vertical direction distributing liquid crystal displaying panel. The pixel structure comprises a first film transistor, a second film transistor, a first pixel electrode, a second pixel electrode and a plurality of directiondistributing components, wherein, the first film transistor and the second film transistor are all communicated with the scanning line and the data line. The first film transistor is provided with a first leakage electrode. The first pixel electrode is electrically connected with the first leakage electrode. The second film transistor is provided with a second leakage electrode, and the second pixel electrode is floatly arranged at the upper part of the second leakage electrode to form a coupling capacitance. A voltage difference exists between the second pixel electrode and the first pixel electrode. The direction distributing components are arranged on the first pixel electrode and the second pixel electrode.

Description

technical field [0001] The present invention relates to a pixel structure of a liquid crystal display panel, and in particular to a pixel structure of a multi-domain vertical alignment (MVA) liquid crystal display panel. Background technique [0002] Existing liquid crystal displays tend to develop towards high brightness, high contrast, large area display and wide viewing angle. In order to improve the viewing angle of the liquid crystal display, various wide viewing angle technologies have been proposed. Wide-viewing-angle liquid crystal displays are currently common such as multi-domain vertical alignment liquid crystal displays, in-plane switching (IPS) liquid crystal displays, fringe field switching (FFS) liquid crystal displays, and the like. [0003] figure 1 It is a schematic top view of an existing existing pixel structure applied to a multi-domain vertical alignment liquid crystal display. Please refer to figure 1 The pixel structure 100 is disposed on a thin fi...
