摘要

The present application provides a display panel. The display panel includes a plurality of data lines, a plurality of constant voltage traces, and a plurality of drive traces located in a display area. The display panel further includes a first metal layer, a second metal layer, and a shield layer between the first metal layer and the second metal layer, wherein the first metal layer includes a gate trace, the shield layer includes a plurality of shield traces, and the second metal layer includes the drive trace. An overlap region of the drive trace and the gate trace on the shield layer overlaps with the shield trace.

說明書

It should be noted that when the drive traces S1 are disposed in the display area AA, and the drive traces S1 cannot completely and uniformly cover the entire display area AA. Therefore, the design may cause a defect of uneven metal traces density in the display area of the display panel, which may further cause a display stripe in the display panel, seriously affecting the display effect. In the present embodiment, the shelter traces Z are provided on the drive traces S1 in a uniform distribution, and the shelter traces Z are closer to a light-emitting side of the display panel than the drive traces S1. Therefore, the design of the present embodiment can alleviate the problem of display stripes caused by the drive traces S1 being provided in the display area AA.

Alternatively, the shelter trace Z may also be electrically connected to the constant voltage trace V. By applying a constant voltage to the shelter trace Z, it is possible to shield the signal of the drive trace S1 and prevent the signal of the drive trace S1 from interfering with the upper-layer trace or the electronic component thereof, for example, to prevent the signal of the drive trace S1 from interfering with the anode 302 in the light-emitting layer 30.
