Embodiment Construction

[0020] see figure 1 , figure 1 is a schematic cross-sectional structure diagram of the design structure near the output end of the gate drive circuit in the implementation mode, as shown in figure 1 As shown, the metal light-shielding sheet 30 is located at the bottom layer, on the metal light-shielding sheet 30 is a silicon nitride layer 60, on the silicon nitride layer 60 is a semiconductor layer 20, the semiconductor layer 20 is covered with an insulating layer 50, and the insulating layer 50 is provided with a conductive hole 40, the gate line 10 is laid on the insulating layer 50, passing through the area where the via hole 40 is located, the via hole 40 penetrates the insulating layer 50 and the silicon nitride layer 60, and avoids the area where the semiconductor layer 20 is located, so that the gate line The wire 10 can directly contact the metal light-shielding sheet 30 through the via hole 40 .

[0021] Wherein, the area, size and shape of the via hole 40 are not f...

Abstract

The invention discloses a liquid crystal display panel. The liquid crystal display panel comprises a gate line, an anti-dazzling screen, an insulation layer and a gate drive circuit. The end, near the gate drive circuit output end, of the gate line of the liquid crystal display panel is in contact with the anti-dazzling screen. The end, away from the gate drive circuit output end, of the gate line of the liquid crystal display panel is completely isolated from the anti-dazzling screen. In this way, output signals emitting from the end, near the gate drive circuit output end, of the gate line and output signals emitting from the end, far away from the gate drive circuit output end, of the gate line have similar signal delay, thus being capable of mitigating the problem of non-uniform display of the liquid crystal display panel. The invention further provides a liquid crystal display device.

Description

technical field [0001] The invention relates to the field of display panels, in particular to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] The gate drive circuit substrate technology (GOA, Gate on Array) that integrates the gate circuit on the liquid crystal display panel has the advantages of reducing IC cost and reducing the area of ​​the circuit board around the panel, but there is also the problem of signal transmission differences. [0003] Specifically, the signal is output from the output terminal of the gate driving circuit and transmitted along the gate line. The gate signal closer to the GOA presents a square wave state. Due to the influence of the RC delay, the position on the same gate line farther from the GOA output terminal will be delayed due to the heavy load, and the predetermined signal cannot be displayed. square wave signal. Due to the difference of signals on the same gate line, it will lead to abno...
