Patent ID: 8130335

Claim:
An electro-optic substrate, comprising: a transparent substrate; a first light-shielding layer disposed on at least one part of a region surrounding an opening in a plane view, at a side of a first surface of the transparent substrate; a first insulating layer having a refraction index n and a layer-thickness t (nm), as an insulating layer sandwiched between the first light-shielding layer and the transparent substrate; a thin-film transistor disposed between the first insulating layer and the transparent substrate, the thin-film transistor having a channel region positioned inside the first light-shielding layer in a plane view, a semiconductor layer with a distance L c (nm) between an end of the first light-shielding layer and an end of the channel region set to fulfill a relational expression 1 that states: nt 2 /244 (nm)<L c (nm); a gate insulating layer covering at least the channel region; a gate electrode disposed to a region opposite to the channel region with the gate insulating layer intervened therebetween; a second light-shielding layer disposed between the semiconductor layer and the transparent substrate; and a second insulating layer disposed between the semiconductor layer and the second light-shielding layer.
