Display substrate and method of manufacturing the same

摘要

A display substrate includes a base substrate, a first insulating layer formed on a base substrate, a pixel including a pixel electrode having the first insulating layer, and a circuit including a circuit transistor disposed on a peripheral area to drive the pixel. The pixel includes a first channel formed on the base substrate having the first insulating layer formed thereon. The first channel includes a poly-silicon layer, a first source electrode and a first drain electrode formed on the first channel that are spaced apart from each other, and a first gate electrode formed on the first source electrode and the first drain electrode corresponding to the first channel which is formed of the transparent conductive material. The poly-silicon layer is formed at a front channel portion of the first channel proximal to the first gate electrode through the first gate electrode.
