Embodiment 1

[0034] figure 2 It is a schematic diagram of a liquid crystal display panel in this embodiment, image 3 for figure 2 A partially enlarged view of the upper left corner of the middle liquid crystal display panel.

[0035] The liquid crystal display panel includes: a first substrate 100 , a second substrate and a liquid crystal layer (not shown) sandwiched between the two substrates. The first substrate 100 is, for example, a thin film transistor array substrate, which includes a plurality of gate lines and data lines (not shown in the figure), wherein the plurality of gate lines are parallel to each other and separated from each other at fixed intervals, and along the Extending along the first direction, and a plurality of data lines are also parallel to each other and separated from each other at fixed intervals, and extend along the second direction substantially perpendicular to the first direction; the TFT array substrate also includes through the gate A plurality of ...

Embodiment 2

[0049] Figure 5 It is a partially enlarged view of the upper left corner of the liquid crystal display panel in this embodiment. As shown in the figure, the difference from Embodiment 1 is:

[0050] In a plane parallel to the liquid crystal display panel 200, the second wiring layer 215b is a right-angled triangle, and its two right-angled sides are basically parallel to the two boundaries of the display area A, that is, the first right-angled side 215b1 is basically parallel to the display area A. The boundary 131 of the area A, the second right-angled side 215b2 is substantially parallel to the boundary 132 of the display area A;

[0051] In addition, the hypotenuse 215b3 of the second wiring layer 215b coincides with the corner apex of the scanning line wiring 216 in the non-display area P. As shown in FIG. After the scan line leads 216 are wired, when each scan line lead extends from the non-display area P to the display area A, there will be a corner, which can be a ri...

Embodiment 3

[0056] Figure 6 It is a partially enlarged view of the upper left corner of the liquid crystal display panel in this embodiment. As shown in the figure, the difference from Embodiment 2 is:

[0057] The first wiring layer 315a includes two parts, namely the first wiring layer 315a1 and the first wiring layer 315a2, wherein one end of the first wiring layer 315a2 is connected to the FPC, one end of the first wiring layer 315a1 is connected to the driver IC, and the other end of the first wiring layer 315a1 is connected to the driver IC. One end is merged in one place and then connected to the common electrode line in the display area A.

[0058] Secondly, the second wiring layer 315b is a right-angled triangle in a plane parallel to the liquid crystal display panel 300, the two right-angled sides are basically parallel to the two boundaries of the display area A, and the first right-angled side 315b1 is basically coincident with the first wiring. The layer 315a1 and the seco...

Abstract

The invention provides a liquid crystal display panel, which comprises a display area and a non-display area on the periphery of the display area, wherein a common electrode lead is arranged inside the non-display area, the common electrode lead at least comprises a first lead layer and a second lead layer, wherein the first lead layer is provided with a medium layer, the second lead layer is arranged on the medium layer, and the first lead layer is electrically connected with the second lead layer. The liquid crystal display panel can ensure that the delay of the Com signal entering the display area after passing through the common electrode lead is controlled within a given range, and can prevent the large signal delay from causing unfavorable phenomenon such as flash, crosstalk and the like of the liquid crystal display panel.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel. Background technique [0002] In recent years, the rapid development of information and communication technology has increased the demand for various types of display devices. Currently common display devices include: cathode ray tube display, liquid crystal display (Liquid Crystal Display, LCD), plasma display, electroluminescent display, and vacuum fluorescent display. Among them, LCD has gradually become the mainstream of display device development due to its high-definition, true-color video display, thin and light appearance, low power consumption, and no radiation. [0003] An LCD generally includes a liquid crystal display panel for displaying pictures and a circuit part for supplying signals to the liquid crystal display panel. The liquid crystal display panel generally includes a first substrate and a second substrate, whi...
