US Patent 7932530 Display substrate and method of manufacturing the same

A display substrate includes a gate electrode, a gate insulating layer, and a semiconductor layer that are sequentially formed on a substrate. Also, the display substrate includes a color filter layer formed on the substrate and exposing a portion of the semiconductor layer, and source and drain electrodes that each overlap with the semiconductor layer and the color filter layer. The gate electrode, the gate insulating layer, and the semiconductor layer have the same shape as each other, and the gate electrode is insulated from the gate insulating layer and the semiconductor layer by the color filter layer.
