Abstract

The invention discloses a pixel array substrate comprising a substrate body, a plurality of scanning wires, a first insulation layer, a plurality of data wires, a plurality of common electrode wires, a plurality of pixel structures, a second insulation layer and a common electrode. The scanning wires are disposed on the substrate body and are covered by the first insulation layer. The data wires and the common electrode wires are disposed on the first insulation layer in an alternative manner. The common electrode wires intersect with the scanning wires and thus a plurality of overlapping areas are defined. Each pixel structure comprises an active component and a pixel electrode. The second insulation layer covers the data wires, the common electrode wires and the active components and is provided with a plurality of contact openings disposed in the overlapping area. The common electrode is electrically connected with the common electrode wires through the contact openings and overlaps an area of the pixel electrodes.

Description

technical field [0001] The present invention relates to a pixel array substrate, and in particular to a pixel structure array substrate for a fringe field switching (Fringe Field Switching, FFS) liquid crystal display panel. Background technique [0002] In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (FlatPanel Display) has been vigorously developed. Liquid crystal displays have gradually replaced traditional cathode ray tube displays due to their advantages of low-voltage operation, no radiation scattering, light weight, and small size, and have become the mainstream of display products in recent years. However, liquid crystal displays still have the problem of limited viewing angles. At present, the technologies that can meet the requirement of wide viewing angle include twisted nematic (TN) liquid crystal plus wide viewing film (wide viewing film), in-plane switching (IPS) liquid crystal ...
