Abstract:
1. An electro-optic device substrate comprising: a substrate; a plurality of data lines and a plurality of scan lines intersecting with each other over the substrate; pixel electrodes formed in pixels that correspond to the intersections between the data lines and the scan lines and that constitute a display area of the substrate; transistors disposed in non-opening areas separating opening areas of the respective pixels, one of the transistors including: a semiconductor layer having a channel region with a channel length following one direction of the display area, a data line-side source-drain region electrically connected to a corresponding data line, a pixel electrode-side source-drain region electrically connected to a corresponding pixel electrode, a first junction region between the channel region and the data line-side source-drain region, and a second junction region between the channel region and the pixel electrode-side source-drain region; and light shielding sections above the semiconductor layers, one of the light shielding sections including: a main section that extends in another direction intersecting the one direction and that covers the channel region, a first section that extends from the main section following the one direction and that covers the first junction region, the first section including a first light shielding portion and a second light shielding portion, the first light shielding portion and the second light shielding portion being opposed to each other with the first junction region therebetween, and a second section that extends from the main section in the one direction, that covers the second junction region, the second section including a third light shielding portion and a fourth light shielding portion, the third light shielding portion and the fourth light shielding portion being opposed to each other with the section junction region therebetween, the third light shielding portion and the fourth light shielding portion being formed wider than the first light shielding portion and the second light shielding portion, respectively, in the another direction and overlapping adjacent pixel electrodes.
