Embodiment Construction

[0019] The invention is further clarified in conjunction with the accompanying drawings and specific embodiments, and it is to be understood that these examples are intended to illustrate the invention and are not intended to limit the scope of the invention, and those skilled in the art will The modification of the equivalent form falls in the range as defined in the claims appended claims.

[0020] In order to make the drawing, only the parts associated with the present invention are schematically shown, which do not represent the actual structure of the product. In addition, it is schematically illustrated in one of some of the same structures or functions to make the drawing, and only one of them is schematically illustrated, or one of them is schematically illustrated. In this article, "one" not only means "only one", but also "more than one" situation.

[0021] A display panel of the present invention, such as figure 1 As shown, it includes a first metal layer (diagram not s...

Abstract

The present invention provides a display panel, which includes a first metal layer, a second metal layer, a gate insulating layer, a first insulating layer covering the second metal layer, an organic insulating layer covering the first insulating layer, and an organic insulating layer located on the organic insulating layer. The common electrode on the top; also includes a second auxiliary metal layer formed simultaneously with the second metal layer and close to the second metal layer; the lower surface of the common electrode between the second metal layer and the second auxiliary metal layer The plane where it is located is lower than the plane where the upper surfaces of the second metal layer and the second auxiliary metal layer are located. The display panel of the present invention opens holes in the insulating layer between two adjacent metal layers formed on the same layer with different functions, so that the plane of the lower surface of the common electrode located between the two adjacent metal layers is lower than The plane where the upper surfaces of the two adjacent metal layers are located can reduce the lateral capacitance between the two adjacent metal layers and greatly reduce the signal influence between the two adjacent metal layers.

Description

Technical field [0001] The present invention relates to the technical field of display panels, and more particularly to a display panel. Background technique [0002] For some display panels, due to the need for testing and repair, the second metal layer 40 is formed simultaneously in each pixel region, and the second metal layer 40 is disposed at each pixel region and the second metal layer 40 is disposed. Auxiliary conductor (CK) 41. Due to the presence of the second auxiliary line 41 [0003] As the display panel integration is improved, two metal layers are not avoided side by side by the need for testing and repair. When these two metal layers are closer to the lower limit of the Design Rule (usually the length of the entire panel), the lateral capacitance between the two cannot be ignored. The presence of lateral capacitance causes two lines to be coupled to each other and ultimately affects the display. Inventive content [0004] It is an object of the present invention t...
