Abstract

The invention provides a display panel and a display device, the display panel is provided with a display area and a non-display area, the display panel comprises a first thin film transistor located in the display area, and a second thin film transistor and a first shielding layer which are located in the non-display area, the first thin film transistor is an oxide transistor, and the second thin film transistor is an oxide transistor. The first thin film transistor comprises a first grid and a first active layer, the second thin film transistor is a silicon transistor and comprises a second grid and a second active layer, and the first shielding layer is located on the side, away from the second active layer, of the second grid. The projection of the first shielding layer and the projection of the second grid electrode in the direction perpendicular to the surface of the second active layer have an overlapping area, the first shielding layer and the first active layer are arranged on the same layer, and the first shielding layer is connected with a fixed potential. The first shielding layer can play a role in electrostatic shielding, so that the antistatic capability of the non-display area is improved, and the display effect of the display panel is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] A display panel (panel) may include a display area and a non-display area. The display area may be provided with a display unit, and the non-display area may be provided with a driving circuit. Generally speaking, the non-display area is provided at the periphery of the display area. Both the display area and the non-display area can be provided with thin film transistors (Thin Film Transistor, TFT). In the display panel formed by using the hybrid TFT display (Hybrid TFT Display, HTD) technology, a variety of different transistors can be provided. Specifically, the display The panel may include oxide transistors and silicon transistors, for example, oxide transistors may be provided in the display area, and silicon transistors may be provided in the non-display area. Wherein, the material of the active layer in the oxide tra...
