Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0020] In order to make the drawing concise, each drawing only schematically shows the parts related to the present invention, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components having the same structure or function is schematically shown, or only one of them is marked. Herein, "a" not only means "only one", but also means "more than one".

Abstract

The invention provides a display panel. The display panel comprises a first metal layer, a second metal layer, a gate insulation layer, a first insulation layer covering the second metal layer, an organic insulation layer covering the first insulation layer and a common electrode located on the organic insulation layer. The display panel further comprises a second auxiliary metal layer which is formed at the same time as the second metal layer and is close to the second metal layer; the plane where the lower surface of the common electrode located between the second metal layer and the secondauxiliary metal layer is located is lower than the plane where upper surfaces of the second metal layer and the second auxiliary metal layer are located. According to the display panel, holes are formed in the insulation layer between every two adjacent metal layers which have different effects and are formed on the same layer, and the plane where the lower surface of the common electrode locatedbetween the two adjacent metal layers is located is lower than the plane where the upper surfaces of the two adjacent metal layers are located, so that the lateral capacitance between the two adjacentmetal layers can be reduced, and the signal influence between the two adjacent metal layers is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel. Background technique [0002] For some display panels, due to the needs of testing and repairing, when the second metal layer 40 is formed, a second metal layer arranged parallel to the second metal layer 40 and arranged close to the second metal layer 40 is simultaneously formed in each pixel area. Auxiliary Carrying Line (CK) 41. Due to the presence of the second auxiliary line 41 [0003] With the improvement of the integration level of the display panel, due to the needs of testing and repairing, it is inevitable that there will be two different metal layers arranged side by side. When the distance between these two metal layers is close (the lower limit of the design rule) and the length is very long (usually the entire panel length), the lateral capacitance between the two cannot be ignored. The presence of lateral capacitance causes the t...
