Abstract

The invention provides a pixel array substrate which is provided with a pixel area and a wiring area which is positioned at the edge of the pixel area. The pixel array substrate comprises a plurality of display pixel units in the pixel area and a plurality of imitation-pixel units in the wiring area; wherein, each imitation-pixel unit comprises a data line and a scanning line, a plurality of switch components and a plurality of pixel electrodes. The switch component is electrically connected with the data line and the scanning line; and the pixel electrode is electrically connected with the switch component. More especially, the electrostatic current in the pixel area can be dispersed by the imitation-pixel unit in the wiring area. The imitation-pixel unit can maintain the electric continuity of the pixel array substrate and provides the protection effect of the electrostatic discharging simultaneously. Therefore, the wiring area of the pixel array substrate has large area.

Description

【Technical field】 [0001] The present invention relates to a pixel array substrate, and in particular to a pixel array substrate with a large wiring area. 【Background technique】 [0002] In recent years, due to the maturity of optoelectronic technology and semiconductor manufacturing technology, the vigorous development of flat-panel displays has been driven. Among them, liquid crystal displays have become the mainstream of display products due to their advantages of low-voltage operation, no radiation scattering, light weight, and small size. [0003] A general liquid crystal display is mainly assembled by a liquid crystal display panel and a backlight module. Among them, the liquid crystal display panel is generally composed of a pixel array substrate including a thin film transistor array, a color filter substrate, and a liquid crystal layer between the two, wherein many scanning lines, data Very fine lines and components such as lines and pixel units.
