Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel. Background technique [0002] Due to the light-sensitive characteristic of the semiconductor material, the characteristics of the semiconductor material of the thin film transistor are affected by the external ambient light and the light emitted by the light emitting device, resulting in a decrease in the display performance of the light emitting device driven by the thin film transistor. [0003] Therefore, it is necessary to propose a technical solution to solve the influence of light on the semiconductor material of the thin film transistor. Contents of the invention [0004] The purpose of the present application is to provide a display panel to improve the effect of light on the active layer of the thin film transistor. [0005] In order to achieve the above object, the technical scheme is as follows: [0006] A display panel comprising: ...
