Problems solved by technology

[0005] The present application relates to a display panel, which is used to solve the problem in the prior art that the connecting lines and the scanning lines of the display panel are arranged in the same layer and parallel, and both the connecting lines and the scanning lines are provided with convex structures for reducing impedance. The protrusions between adjacent connecting lines and scanning lines form a closed space together, so that the etching solution is easy to remain, resulting in local over-etching, forming broken lines, and affecting the display quality of the display panel.

Abstract

A display panel and a manufacturing method thereof. The display panel includes: a plurality of parallel scanning lines, a plurality of parallel data lines, a common electrode and a plurality of connecting lines; A circle of second metal layer is also arranged in the non-display area of ​​the layer; a plurality of connection lines are arranged parallel to the data lines; a plurality of protruding structures are arranged at intervals along the first direction on the scanning lines; the beneficial effect is: connecting the connection lines with the The scanning line is set vertically to avoid parallel setting of the connecting line and the scanning line. The position close to the connecting line and the scanning line forms a closed space, resulting in etching liquid remaining in the display panel and affecting the display quality of the display panel; in addition, the scanning line along the first A plurality of protruding structures are arranged at intervals in the direction, the first protruding structure faces the positive direction of the second direction, and the second protruding structure faces the negative direction of the second direction, further reducing the possibility of etching liquid remaining in the display panel , improving the production yield of the display panel.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel. Background technique [0002] In the field of medium and large-sized low-temperature polysilicon display panels, due to the relatively large size of the display panel, the horizontal and vertical distances are relatively large. A Vcom GE line is designed below the scanning line (the gate common connection line, the left and right ends are connected to the second metal layer through the openings in the second insulating layer), and the second metal layer is conducted through openings in the second insulating layer. layer is connected to the common electrode in the plane by opening holes in the second insulating layer, so that the common electrode on the entire plane can receive the signal input from the second metal layer in a timely and uniform manner. Among them, due to the etching characteristics of wet etching (WET, etchant, chemical etching) (isotropic etching,...
