Abstract
A method for manufacturing a pixel structure is provided. A thin film transistor is formed on a substrate and an insulating layer is formed to cover the substrate and the thin film transistor. The insulating layer is patterned by a half-tone mask to form a protruding pattern, a sunken pattern connecting the protruding pattern, and a contact window inside the sunken pattern. A transparent conductive layer is formed to cover the protruding pattern and the sunken pattern, and filled in the contact window. A passivation layer is formed to cover the transparent conductive layer. A pixel electrode pattern is formed from the transparent conductive layer by removing a part of the passivation layer located on the protruding pattern, a part of the transparent conductive layer on the protruding pattern, and a part of the passivation layer located within the contact window. A pixel structure manufactured by the method is provided.
