Abstract

The embodiment of the invention provides an array substrate, a manufacturing method of the array substrate and a display device. The array substrate comprises a substrate and a plurality of thin filmtransistors located on one side of the substrate. The thin film transistor comprises an active structure which is arranged on one side of the substrate and comprises a first region and a second region, wherein the resistivity of the first region is smaller than that of the second region, the first region comprises a source region and a drain region, and the second region comprises a channel regionand an auxiliary region, the channel region being located between the source region and the drain region, and the auxiliary region surrounding at least part of the source region and / or the drain region; a source-drain electrode which comprises a source electrode and a drain electrode, wherein the source electrode is connected to the source region, and the drain electrode is connected to the drainregion; a first insulating layer arranged on one side of the active structure; and a grid electrode arranged on the side, deviating from the active structure, of the first insulating layer, wherein the orthographic projection of the grid electrode on the substrate covers the orthographic projection of at least part of the channel region on the substrate. The cut-off current of the thin film transistor can be reduced.

Description

technical field [0001] The present invention relates to the technical field of semiconductor devices, in particular to an array substrate, a method for manufacturing the array substrate, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) is an active light-emitting device. Compared with the traditional liquid crystal display (Liquid Crystal Display; LCD) display method, the OLED display technology does not need a backlight, and has the characteristic of self-luminescence. OLED uses a thin film of organic material and a glass substrate. When an electric current passes through it, the organic material will emit light. Therefore, OLED display panels can significantly save power, can be made lighter and thinner, can withstand a wider range of temperature changes than LCD display panels, and have a larger viewing angle. OLED display panel is expected to become the next-generation flat panel display technology after LCD, and it is one of the ...
