Abstract
A display panel and a display device. The display panel includes a power supply high-voltage signal line, a driving thin film transistor, and a light emitting element. The driving thin film transistor comprises an active layer. The active layer includes a source region, a drain region, and a channel region. The source region is connected to the power supply high-voltage signal line. The drain region is connected to the light emitting element. A part of the channel region close to the drain region has a lower majority carrier concentration than a part of the channel region close to the source region.
