    摘要: To prevent an n-channel thin-film transistor from being deteriorated by hot holes generated in a gate-negative pulse mode. A thin polysilicon film 10 is provided with a p-type semiconductor region 13 in contact with a channel region 14. The p-type semiconductor region 13 is electrically connected to nowhere except the channel region 14. Holes induced on the surface due to a gate-negative pulse are further supplied from the p-type semiconductor region 13. An electric field established by the gate-negative pulse is relaxed by the holes, fewer hot holes are injected into the gate oxide film, and the TFT characteristics are less deteriorated.

    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.
