Abstract

A mask set, a pixel unit and a manufacturing method thereof, an array substrate and a display device are provided to overcome the problem of low brightness of a display screen of a display device. In the pixel unit, the maximum size value of an overlapped area between an active layer and a drain electrode of a thin-film transistor (TFT) in the direction parallel to data line is less than the size value of one side, overlapped with the data line, in an overlapped area between the active layer and a source electrode; and the source electrode is the portion of the data line disposed in an overlapped area between the active layer and the data line. The pixel unit has the advantages of a larger opening area and higher light transmittance. Thus, the brightness of a display screen of the display device comprising the pixel units can be enhanced. Moreover, the problem of screen flicker can be avoided to some extent, and hence the display quality of images can be improved.
