THIN FILM TRANSISTOR ARRAY

摘要

A thin film transistor array board is provided. A thin film transistor array board according to an embodiment of the present invention includes a substrate, a gate electrode which is located on the substrate, a gate insulating layer which is located on the gate electrode, a semiconductor layer which is located on the gate insulating layer and includes a channel region, a source electrode and a drain electrode which are located on the semiconductor layer and face each other, and a protection layer which covers the source electrode, the drain electrode, and the semiconductor layer. The semiconductor layer includes a first part which is overlapped with the source electrode and the gate electrode, and a second part which is overlapped with the drain electrode and the gate electrode. The first part of the semiconductor layer includes a hill part which protrudes from the first part.
