Abstract: A method of manufacturing a thin film transistor array substrate and a structure of the same are disclosed. The manufacturing method merely requires two steps of mask fabrication to accomplish the manufacture of thin film transistor array, in which the manufacturing method utilizes a first mask fabrication step to define a pattern of a source electrode and a drain electrode of the thin film transistor, and a partially-exposed dielectric layer, and utilizes a second mask fabrication step to define an arrangement of a transparent conductive layer. The manufacturing method and structure can dramatically reduce the manufacturing cost of masks and simplify the whole manufacturing process.

Abstract: The present invention provides a method of making a pixel structure of a reflective type electrophoretic display device. First, a first metal pattern layer, an insulating layer, a semiconductor pattern layer and a second metal pattern layer are formed sequentially on a substrate. Next, a passivation layer is formed on the substrate, the semiconductor pattern layer and the second metal pattern layer, and an organic photoresist layer is formed on the passivation layer, wherein the organic photoresist layer has a first contact hole exposing the passivation layer. Then, the organic photoresist layer is utilized as a mask to remove the exposed passivation layer and to form a second contact hole in the passivation layer to expose the second metal pattern layer. Subsequently, a third metal pattern layer and a transparent conductive pattern are formed sequentially on the organic photoresist pattern layer and the exposed second metal pattern layer.
