Abstract
Provided is a display panel, which includes a substrate, a first signal trace, a first insulating layer, a second insulating layer, and an isolation protection portion. In the first region, the second insulating layer directly contacts the first signal trace, and in the second region, the first insulating layer is located between the second insulating layer and the first signal trace. In the second region, the isolation protection portion overlaps with the first signal trace and is located on a side of the first insulating layer away from the substrate. A first voltage signal received by the first signal trace and a second voltage signal received by the isolation protection portion have opposite voltage types.
Claims20
