Abstract:
1. An active matrix substrate, comprising: a plurality of scanning lines extending parallel to each other; a plurality of signal lines extending parallel to each other in a direction crossing the scanning lines; a plurality of thin film transistors each provided at each of intersections of the scanning lines and the signal lines, and each including a semiconductor layer and a source electrode and a drain electrode which are formed on the semiconductor layer in a layer in which the signal lines are formed; and a coating type insulating layer formed between each of the scanning lines and each of the signal lines, wherein each of the semiconductor layers includes a channel region, a plurality of openings are formed in the insulating layer such that the semiconductor layers and the channel regions thereof are each exposed, at least part of a peripheral end of the plurality of openings of the insulating layer is positioned on an inner side relative to each of peripheral ends of the semiconductor layers, and the source electrode and the drain electrode are connected to the semiconductor layer through a corresponding one of the plurality of openings.
