LCD panel

Abstract

The invention discloses a liquid crystal display panel which includes a display region, a stay wire region and an external circuit region, wherein, the stay wire region is located between the display region and the external circuit region. The liquid crystal display panel includes a plurality of pixel structures, external connecting pads and stay wire groups. Each of the stay wire groups includesa plurality of lower layer principal stay wires located on a plane and a plurality of upper layer principal stay wires located on another plane, wherein, the two planes are mutually parallel. In addition, each upper layer principal stay wire is corresponding to the lower layer principal stay wire, and vertical projection of the upper layer principal stay wire on the plane can overlap the corresponding lower layer principal stay wire. Light leakage at edges of the display region can be reduced efficiently and the display quality of the panel can be promoted by an appropriate winding manner of the principal stay wire groups.

Description

technical field [0001] The invention relates to a liquid crystal display panel, and in particular to a liquid crystal display panel capable of reducing light leakage at the edge of a display area. Background technique [0002] The rapid progress of the multimedia society is mostly due to the rapid progress of semiconductor devices or display devices. As far as displays are concerned, thin film transistor liquid crystal displays (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. [0003] figure 1 It is a structural schematic diagram of a thin film transistor array substrate of a known liquid crystal display panel. Please refer to figure 1 The thin film transistor array substrate 100 of the liquid crystal display panel has a display area 102 and a non-display area 103 , wherein the displa...

AI Technical Summary

Problems solved by technology

However, in the known technology, the signal is transmitted to the pixel structure 110 by using the double-layer metal winding structure. Although the metal winding 130 can be maintained at an equal impedance, the double-layer metal winding structure is easy to be separated between the wire of the metal winding 130 and the pixel structure 110. A backlight penetration area is formed between the wires, resulting in light leakage, and the resistance-capacitance product value of each metal winding wire 130 is very different, which will cause a band-like unevenness (band mura) on the display screen, seriously affecting the display quality of the display.
