ABSTRACT:
A liquid crystal display structure is provided. The liquid crystal display structure includes a pixel region and a thin film transistor on the substrate. The thin film transistor is adjacent to the pixel region and includes a gate electrode; a gate insulating layer having a top surface; a source electrode and a drain electrode at the top surface of the gate insulating layer; a semiconductor layer disposed at the top surface of the gate insulating layer, the semiconductor layer between the source electrode and the drain electrode defining a channel region, the semiconductor layer including a small molecule organic semiconductor material; and a first passivation layer covering the channel region, a top surface of the first passivation layer coinciding with or being below a top surface of each of the source electrode and the drain electrode.
