Abstract
A backplane includes: a substrate, a pixel electrode, which includes a transparent conductive material, on the substrate, a capacitor first electrode formed on the same layer as the pixel electrode, a first protection layer covering the capacitor first electrode and an upper edge of the pixel electrode, a gate electrode of a thin film transistor (TFT) formed on the first protection layer, a capacitor second electrode formed on the same layer as the gate electrode, a first insulating layer that covers the gate electrode and the capacitor second electrode, a semiconductor layer that is formed on the first insulating layer and includes a transparent conductive material, a second insulating layer covering the semiconductor layer, source and drain electrodes of the TFT that are formed on the second insulating layer, and a third insulating layer that covers the source and drain electrodes and exposes the pixel electrode.
