Organic thin film transistor, manufacturing method thereof, array substrate and display device

Abstract

An embodiment of the invention provides an organic thin film transistor, a manufacturing method thereof, an array substrate and a display device and relates to the technical field of thin film transistors. The problem that an organic semiconductor layer is poor in forming effect and prone to line breaking due to large contact angle of an electrode layer in a thin film transistor is solved, quality and performance of the thin film transistor is guaranteed, wasting of raw materials is avoided, and production cost is lowered. The organic thin film transistor comprises a source electrode, a drain electrode, the organic semiconductor layer arranged above the source electrode and the drain electrode, and a modifying layer, and the modifying layer is arranged at a position, corresponding to the source electrode and the drain electrode, below the organic semiconductor layer, covers the source electrode and the drain electrode and is used for changing the contact angle of the source electrode and the drain electrode. The organic thin film transistor is applied in the technical field of display.

Description

technical field [0001] The invention relates to the technical field of thin film transistors, in particular to an organic thin film transistor, a manufacturing method thereof, an array substrate and a display device. Background technique [0002] In recent years, with the continuous development of science and technology, the performance of electronic devices has been gradually improved. In the structure of the display panel of the thin film transistor device in the prior art, the source and drain electrodes are generally made of metal materials, which ensures Conductivity of source and drain electrodes. Meanwhile, in order to ensure the performance of electronic devices, an organic semiconductor layer is usually formed on the source and drain electrodes. [0003] However, due to the relatively large contact angles of the source and drain electrodes, there will be a problem that the spreading behavior of the organic semiconductor layer will be poor when forming the organic s...
