Abstract

See full text

The present disclosure discloses a mask plate, a method of manufacturing a corresponding array substrate, and an array substrate, used in the technical field of liquid crystal displays. The mask plate comprises a non-transparent area and a transparent area. The non-transparent area has an intermediate vertical trunk, an intermediate horizontal trunk, and branches extending from the intermediate vertical trunk and the intermediate horizontal trunk. The intermediate vertical trunk and the intermediate horizontal trunk form certain angles with the branches, respectively. The transparent area has a first transparent portion provided between the branches. The first transparent portion is provided with an optical interference unit, which is used for processing light with a first intensity into light with a second intensity, the first intensity being higher than the second intensity. A second transparent portion is used for directly introducing light with the first intensity to form a contact hole on an array substrate to be formed through the mask plate. The present disclosure further comprises a method of manufacturing an array substrate using the mask plate, and an array substrate thus manufactured. According to the present disclosure, both the aperture ratio of a pixel unit and transmittance of the liquid crystal panel can be improved.
