Patent ID: 8848124

Claim:
An active matrix substrate comprising: a plurality of pixels which are arranged on a substrate and each of which includes a thin film transistor, wherein the thin film transistor includes a gate electrode, a gate insulating layer on the gate electrode, a semiconductor active layer on the gate insulating layer, a source electrode connected to the semiconductor active layer, a drain electrode connected to the semiconductor active layer, a pixel electrode connected to the drain electrode, and an interlayer insulating layer for insulating the source electrode from the pixel electrode, wherein a protective film is formed on the semiconductor active layer so as to divide the semiconductor active layer into two exposed regions, the source electrode is connected to one of the two exposed regions, the drain electrode is connected to the other of the two exposed regions, and the drain electrode is connected to the pixel electrode on the protective film, a connection point between the drain and the pixel electrode is above the protective film, wherein the plurality of thin film transistors are arranged in a straight line shape, wherein a plurality of independent semiconductor active layers which respectively constitute the plurality of thin film transistors are arranged in parallel and in a straight line shape, and wherein the protective film is continuously formed in a stripe shape over the plurality of semiconductor active layers so as to divide each of the plurality of semiconductor active layers into two exposed regions.
