The invention provides a thin film transistor and a production method therefor, an array substrate, a display panel and device. The method comprises: a step of forming an organic semiconductor layer on a hydrophilic structure layer, wherein the step of forming the organic semiconductor layer on the hydrophilic structure layer comprises: forming an oleophylic material layer on the upper surface of the hydrophilic structure layer; patterning the oleophylic material layer, removing the oleophylic material beyond an area with the organic semiconductor layer to be formed, and retaining the oleophylic material in the area with the organic semiconductor layer to be formed to obtain an oleophylic layer; and forming the organic semiconductor layer on the oleophylic layer by using the oleophylic material layer through a wet process. The production method of the thin film transistor provided by the invention can be used for simply preparing the thin film transistor in the wet process.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a thin film transistor and a manufacturing method thereof, an array substrate, a display panel and a device. Background technique [0002] With the development of display manufacturing technology, liquid crystal display technology has developed rapidly, and has replaced traditional picture tube displays and become the mainstream of future flat panel displays. In the field of liquid crystal display technology, TFT-LCD (ThinFilmTransistorLiquidCrystalDisplay) is widely used in televisions, computers and other fields due to its large size, high integration, powerful functions, flexible process, and low cost. [0003] An organic thin film transistor refers to a transistor in which the semiconductor layer is made of organic materials. Compared with traditional thin film transistors, organic thin film transistors are cheaper to manufacture and have wider application value. However, ...
