DISPLAY SUBSTRATE, METHOD OF FABRICATING AND ELECTROPHORETIC DISPLAY HAVING THE SAME

摘要

A display substrate, a method of manufacturing the display substrate and an electrophoretic display device having the display substrate are provided to form a gate electrode and a pixel electrode at the same time by using the same material, thereby reducing the number of manufacturing steps and the number of masks, improving productivity and decreasing the manufacturing cost. A display substrate(100) includes a base substrate(110), a TFT(Thin Film Transistor)(120) and a pixel electrode(130). The base substrate includes a pixel region which displays an image. The TFT is formed in the pixel region and switches a pixel voltage corresponding to the image. The TFT includes a source electrode(121), a drain electrode(122), an active layer(123) and a gate electrode(125). The source electrode and the drain electrode are formed on the base substrate and the drain electrode is electrically connected to the pixel electrode. The active layer covers the source electrode and the drain electrode. The gate electrode is formed of the same material as the pixel electrode and disposed on the active layer. The gate electrode and the pixel electrode are formed at the same time. The pixel electrode is formed in the pixel region, electrically connected to the TFT, and outputs the pixel voltage.
