Problems solved by technology

However, on the data line of this type of pixel electrode, because the electrode does not completely cover the data line, the electric field of the data line leaks out, resulting in light leakage and liquid crystal inversion instability.
Often due to the phenomenon of light leakage, the contrast of the picture cannot be improved

Embodiment Construction

[0046] A pixel array substrate and a liquid crystal display device of the present invention will be explained below through embodiments. It should be noted that the embodiments of the present invention are not intended to limit the present invention to be implemented in any specific environment, application or special method as described below. Therefore, the descriptions about the embodiments are only for the purpose of explaining the present invention rather than limiting the present invention.

[0047] It should be noted that, in order to facilitate the description of the implementation mode, the following Y-axis represents the direction of the parallel metal traces in the embodiment, but its position is not equal to the Y-axis, and the X-axis represents the long axis direction away from the metal traces. The data line 14 is a preferred embodiment of a metal wire, but is not limited thereto.

[0048] Please refer to figure 1 , is a schematic plan layout diagram of a pixel...

Abstract

The invention provides a pixel array substrate and a liquid crystal display device. The pixel array substrate comprises at least one pixel, each pixel is provided with at least one pixel electrode unit, and each pixel electrode unit comprises a main part, a gradually reducing part and a branch part. By means of the arrangement, the width of each main part is larger than the width of a metal wire so as to avoid electric field leakage of a data line, meanwhile the progressive design of the branch parts is used so as to prevent alignment errors generated between the liquid crystal display device and other laminated boards above and below the device during assembly, and then the contrast ratio of liquid display images is increased.

Description

[0001] This application is a divisional application, its parent application number is 201310270011.7, the filing date is June 28, 2013, and the title of the invention is "pixel array substrate and liquid crystal display device". technical field [0002] The present invention relates to a pixel array substrate, in particular to a pixel array substrate for a liquid crystal display device. Background technique [0003] The rapid progress of the multimedia society is mostly due to the dramatic progress of semiconductor elements or display devices. As far as display devices are concerned, thin film transistor liquid crystal display devices (Thin Film Transistor Liquid Crystal Display, TFT-LCD) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. [0004] At present, the pixel electrodes of some liquid crystal display devices are designed to be in the...
