Publication number: 20190196281Abstract: In an element substrate of an electro-optical device, a semiconductor layer of a transistor has an L shape bending to overlap with both a scanning line and a data line. A first light shielding layer overlaps with a lower layer side of the semiconductor layer. A first light shielding wall and a second light shielding wall are provided on both sides of a semiconductor layer portion between a channel region and a second source/drain region (drain region) of the semiconductor layer. The first light shielding wall and the second light shielding wall to which a constant potential is applied prevent the semiconductor layer portion from being electrically affected even when the first light shielding wall and the second light shielding wall come close to the semiconductor layer portion.Type: ApplicationFiled: December 26, 2018Publication date: June 27, 2019Applicant: SEIKO EPSON CORPORATIONInventors: Hiroyuki OIKAWA, Toru NIMURA, Shinsuke FUJIKAWA
