Abstract
The present invention provides a manufacturing method of an array substrate and an array substrate. The manufacturing method of the array substrate according to the present invention combines the COA technology and the BOA technology, where a black matrix is first formed on a backing plate, followed by forming a top-gate TFT device on the black matrix, and finally forming a color filter layer on the TFT device, wherein the pixel electrode is directly arranged on the drain electrode and connected with the drain electrode. The manufacturing method helps enhance electrical performance of a TFT device and stability of performance, improves quality of a display panel, and, compared to an existing array substrate manufacturing method, reduces masks and operations involved. The manufacturing method is simple and helps reduce manufacturing costs. The array substrate of the present invention requires a simple manufacturing method, provides enhanced electrical performance of a TFT device and stability of performance, and improves quality of a display panel.
