Display panel and display device

A display device, comprising a display panel, wherein the display panel, comprises:

• a pixel circuit and a light-emitting element;
• wherein the pixel circuit comprises a data write device, a drive device, and a bias adjustment device;
• the drive device comprises a drive transistor;
• the data write device is configured to provide a data signal for the drive device;
• the bias adjustment device is configured to provide a bias adjustment signal to the drive device;
• and
• wherein the pixel circuit comprises a first light-emitting control device, the first light-emitting control device is connected between a first power supply voltage signal line and the drive device, and the first power supply voltage signal line is configured to provide a high-level signal, and the drive transistor is a P-type transistor, the bias adjustment signal is V0, and the high-level signal provided by the first power supply voltage signal line is Vdd;
• and
• V0Vdd×1.2;
• or,
• wherein the pixel circuit comprises an initialization device, the initialization device is connected between an initialization signal line and the light-emitting element, and the initialization signal line is configured to provide a low-level signal, and the drive transistor is an N-type transistor, the bias adjustment signal is V0, and the low-level signal provided by the initialization signal line is Vini;
