Abstract
A display panel includes: an active area; a peripheral area; a solder pad area at a side of the peripheral area away from the active area; a first source-drain electrode layer, a passivation layer and a second source-drain electrode layer and a dielectric layer stacked on a back plate in the peripheral area; a touch electrode in the active area; a touch electrode line connected to the touch electrode. The touch electrode line extends from the active area to the peripheral area, and is connected to the solder pad area through the second source-drain electrode layer in the peripheral area. The touch electrode line is connected to the second source-drain electrode layer through a first through hole in the dielectric layer. A portion of a surface of the second source-drain electrode layer, which is away from the passivation layer and exposed through the first through hole, is a flat surface.
