Abstract

The embodiment of the invention discloses an array substrate and a display panel. The array substrate comprises a first thin film transistor arranged on the substrate, and the first thin film transistor comprises a first active layer, a first gate insulation layer and a first gate layer, wherein the surface area, close to the first gate layer, of a first channel region of the first active layer islarger than the area of the vertical projection of the first channel region on the substrate, the surface area of the first gate layer close to the first active layer is greater than the area of thevertical projection of the first gate layer on the substrate, and along the direction perpendicular to the substrate, the distances from all points on the surface, close to the first active layer, ofthe first gate layer to the surface, close to the first gate layer, of the first channel region are equal. Compared with the prior art, the characteristics of the switching thin film transistor are improved, and the driving characteristics of the array substrate and the display effect of the display panel are improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to an array substrate and a display panel. Background technique [0002] With the continuous development of display technology, display panels have been more and more widely used, and people's requirements for display panels are also getting higher and higher. [0003] The display of the existing display panel is provided with driving signals by a driving array on an array substrate. The driving array includes a large number of thin film transistors (Thin Film Transistor, TFT), one of which is a switch thin film transistor (SwitchThin Film Transistor, STFT). However, in the prior art, the characteristics of the STFT are not good, which affects the driving characteristics of the array substrate and the display effect of the display panel. Contents of the invention [0004] Embodiments of the present invention provide an array substrate and a display p...
