Abstract

The invention discloses an array substrate, a manufacturing method therefore, and a display panel. The array substrate includes a plurality of thin film transistor, and each thin film transistor comprises a gate electrode, an oxide semiconductor layer, and an etching barrier layer, wherein the etching barrier layer is located on the oxide semiconductor layer which includes a channel region and a non-channel region, the non-channel region includes an electrode region and a connection region, and the electrode region includes a first electrode region and a second electrode region. Each connection region includes a first connection region and a second connection region, and the first electrode region, the first connection region, the channel region, the second connection region and the secondelectrode region are sequentially arranged in a first direction, and the first direction is parallel to the array substrate. A region, covered by the corresponding etching barrier layer, of each oxide semiconductor layer is a channel region. Each gate electrode is located at one side, far from the corresponding etching barrier layer, of the corresponding oxide semiconductor layer. The width of atleast one connection region is less than the width of the channel region in a second direction. The overlapping area of the gate electrodes with the non-channel regions is reduced, and the parasiticcapacitance is also reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to an array substrate, a manufacturing method thereof, and a display panel. Background technique [0002] Currently, display panels mainly include two types: LCD display panels (Liquid Crystal Display, liquid crystal display panels) and OLED (Organic Light-Emitting Diode, organic light-emitting diode) display panels. In display panel technology, TFT (Thin Film Transistor, Thin Film Field Effect Transistor) is the core component of the display panel, and is generally arranged in an array on the substrate as a switching device for the pixel unit of the display panel. The thin film transistor includes: a gate, a source, a drain and an active layer. The source and the drain are respectively connected to the active layer. When a voltage is applied to the gate, as the gate voltage increases, the surface of the active layer will be consumed The exhaust layer is transform...
