Abstract

This invention puts forward an active element array base plate and its manufacturing method, which provides a base plate with several scan wirings, data wirings and active elements on it, in which, the active elements are connected with the corresponding scan wirings and data wirings, then forms an organic material layer on it covering the wirings and the active elements, then, processes the surface of the organic material layer to form several hollow patterns smaller than 1mum and several pixel electrodes on it connected with the corresponding active elements electrically.

Description

technical field [0001] The invention relates to an active element array substrate and a manufacturing method, in particular to a thin film transistor array substrate and a manufacturing method. Background technique [0002] Displays are designed to give people the most comfortable visual experience, so defects that can be perceived by human vision have always been an important issue in the industry. Taking a liquid crystal flat panel display as an example, the production of a liquid crystal display at least involves complex processes such as a backlight module, a liquid crystal layer, and two glass substrates. If a small flaw occurs in one process, the panel image quality will be negatively affected, and visual defects will also appear during the final light-on test. Visual defects include display unevenness (mura) and the like. [0003] In addition, a layer of organic material is often formed on the thin film transistor array substrate of the liquid crystal display to pla...
