Abstract

The embodiment of the invention provides an array substrate, a display panel and a display device. The array substrate comprises a substrate base plate, a semiconductor layer, a grid metal layer, a source-drain metal layer and a pixel electrode layer. An active layer of a thin film transistor is arranged on the semiconductor layer, a first electrode and a second electrode of the thin film transistor are arranged on the source-drain metal layer, a grid line is arranged on the grid metal layer, and the grid line is overlapped with a channel region of the active layer of the thin film transistor;the first electrode of the thin film transistor is electrically connected to the pixel electrode, wherein the orthographic projection of the first electrode on the substrate base plate is a special-shaped pattern, and the orthographic projection of the first electrode on the substrate base plate and the orthographic projection of the grid line on the substrate base plate are not overlapped with each other. According to the embodiment of the invention, the delay of a grid drive signal transmitted on the grid line can be reduced, thereby facilitating the improvement of the display uniformity.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] With the development of display technology, display panels with advanced functions have gradually become an important feature of today's consumer electronics products, among which liquid crystal display panels have gradually become an important feature of various electronic devices such as mobile phones, personal digital assistants (PDAs), digital cameras, computer screens Or a display panel with a high-resolution color screen widely used in notebook computer screens. [0003] Currently, a liquid crystal display panel driven by a thin film transistor (Thin Film Transistor, TFT) is the most common liquid crystal display panel, and the TFT array substrate of the liquid crystal display panel is usually provided with TFTs, gate lines, data lines, and pixel electrodes. The gate of the TFT...
