Problems solved by technology

[0006] Although the pixel structure 9 shown in FIG. 1 and FIG. 2 reduces the stray capacitance Cpd between the pixel electrode 96 and the data line 93 by setting the organic insulating layer 97, the second electrode between the pixel electrode 96 and the storage line 92 The storage capacitance Cst between the two parts 92b is also reduced at the same time, so the coupling ratio of the data lines in a single pixel area cannot be effectively reduced

Abstract

The invention relates to a pixel structure of a liquid crystal display, which comprises a substrate, a shading part, a first data wire, a second data wire and a pixel electrode. The shading part is arranged on the substrate; the first data wire and the second data wire are arranged along the shading part; and the second data wire is partially overlapped with the shading part; and the pixel electrode is partially overlapped with the first data wire and the shading part, and not overlapped with the second data wire.

Description

technical field [0001] The invention relates to a pixel structure of a liquid crystal display, in particular to a pixel structure of a liquid crystal display with high aperture ratio and low data line coupling ratio. Background technique [0002] With the advancement of electronic technology, especially the prevalence of portable electronic products in daily life, the demand for display devices that are thin, light, small, and low in power consumption is increasing day by day. Liquid Crystal Display (LCD) devices are suitable for such electronic products due to their advantages of low power consumption, thin thickness, and light weight, and have even gradually replaced traditional cathode ray tube display devices. [0003] Since the aperture ratio of a pixel is an important factor affecting the characteristics of a liquid crystal display, various pixel structures have been proposed in the industry to increase the aperture ratio of a pixel. refer to Figure 11 And FIG. 2, FI...
