Abstract
A display panel and a display device are provided. The display panel includes a plurality of light-emitting devices and a pixel driving circuit for driving the light-emitting devices to emit light. By using oxide transistors as a compensation transistor, first initialization transistor, and second initialization transistor in the pixel driving circuit, and using low-temperature polysilicon transistors as other transistors, both low leakage current characteristics of the oxide transistors and high mobility characteristics of the low-temperature polysilicon transistors can be achieved, making the circuit more stable.
