Abstract

The present invention discloses an array substrate and a display device. The array substrate comprises a substrate and a gate layer, a source and drain layer and a TFT (Thin Film Transistor) which are arranged on the substrate. The gate layer comprises the gate of the TFT, and the source and drain layer comprises the source electrode and the drain electrode of the TFT; the drain electrode of the TFT comprises a drain electrode main body and an extension portion, the drain electrode main body and the gate of the TFT are overlapped, and the extension portion is overlapped with the gate layer at a non-TFT area. The array substrate and the display device can solve the problem that the overlapping area of the drain electrode and a gate line has fluctuation.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] In a display device adopting an active matrix driving method, TFT (Thin Film Transistor, Thin Film Transistor) is usually used to complete pixel driving. Therefore, in a display device of an active matrix driving method, a large number of TFTs need to be produced. [0003] However, the inventor of the present invention found that the prior art has at least the following technical problems in the process of realizing the present invention: [0004] In the process of manufacturing a TFT, due to process or equipment deviations, etc., the drain of the TFT will shift, causing the overlap area between the drain and the gate line to fluctuate, affecting the stability of the TFT. Contents of the invention [0005] In view of this, one of the objectives of the present invention is to provide an array subst...
