Electro-optical device and electronic apparatus

An electro-optical device comprising:

• a first substrate;
• a pixel electrode provided on one surface side of the first substrate;
• a scanning line provided in a layer between the first substrate and the pixel electrode, the scanning line extending in a first direction;
• a data line provided in a layer between the first substrate and the pixel electrode, the data line extending in a second direction intersecting the scanning line;
• a transistor including a semiconductor layer extending in each of the first direction and the second direction;
• a first light shielding layer provided in a layer between the first substrate and the transistor, the first light shielding layer overlapping in a plan view with the semiconductor layer;
• a first conductive layer provided in a layer between the transistor and the pixel electrode, the first conductive layer being supplied with a constant potential;
• and
• a first interlayer insulating film provided in a layer between the first light shielding layer and the first conductive layer, wherein
• the first light shielding layer is electrically coupled to the first conductive layer via a first contact hole and a second contact hole provided in the first interlayer insulating film in a manner extending along the semiconductor layer, and
• at least a source/drain region in the semiconductor layer extends in a plan view between the first contact hole and the second contact hole.
