摘要:
A liquid crystal display apparatus includes semiconductor elements placed at intersection points between scanning wires and signal wires. Each semiconductor element includes: a semiconductor layer having a channel region and a pair of semiconductor regions which sandwich the channel region and which are each made of a high-resistance region and a low-resistance region; a first electrode formed on the intrinsic semiconductor region with an insulating film interposed therebetween; and second and third electrodes connected to the low-resistance regions. Each scanning wire constitutes the first electrode of the corresponding one of the semiconductor elements. The first electrode has a first wiring formed on the insulating film and second wiring formed in direct contact with a side surface of the first wiring, part of the second wiring being overlaid on part of a high-resistance region with the insulating film interposed therebetween.
