Patent ID: 7728400

Claim:
An electro-optical device comprising: a first substrate and a second substrate that are opposed to each other; an electro-optical layer disposed between the first substrate and the second substrate; data lines disposed between the first substrate and the electro-optical layer; transistors electrically connected to corresponding ones of the data lines, each transistor including a semiconductor layer having a channel region, a first source/drain region, a first LDD region adjacent to the first source/drain region, a second source/drain region, and a second LDD region adjacent to the second source/drain region; a lower side light shielding film formed in a layer between the first substrate and the semiconductor layer, the lower side light shielding film shielding light from entering the first LDD regions from a first substrate side; island light shielding films provided between the second substrate and the electro-optical layer, the island light shielding films being isolated from each other and overlapping the corresponding first LDD region in plan view; and scanning lines that intersect with the data lines, the lower side light shielding film overlapping a corresponding one of the scanning lines in plan view.
