Abstract

The embodiment of the invention discloses an array substrate and a display panel. The array substrate includes: a first thin film transistor disposed on the substrate, the first thin film transistor includes a first active layer, a first gate insulating layer and a first gate layer; wherein, the first channel of the first active layer The surface area of ​​the region close to the first gate layer is greater 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 vertical area of ​​the first gate layer on the substrate Projected area; and along the direction perpendicular to the substrate, the distances from each point on the surface of the first gate layer close to the first active layer to the surface of the first channel region close to the first gate layer are all the same. Compared with the prior art, the embodiment of the present invention improves the characteristics of the switching thin film transistor, improves the driving characteristics of the array substrate and the display effect of the display panel.

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...
