Patent ID: 7268843

Claim:
An electro-optical device comprising, above a substrate: a data line extending in a first direction; a scanning line extending in a second direction and intersecting the data line; a pixel electrode and a thin film transistor disposed so as to correspond to an intersection region of the data line and the scanning line; a storage capacitor electrically connected to the thin film transistor and the pixel electrode, the storage capacitor including a pixel-potential-side capacitor electrode and a fixed-potential-side capacitor electrode; a light-blocking shield layer disposed above the thin film transistor at a position between the data line and the pixel electrode, the light-blocking shield layer covering the data line, the light-blocking shield layer including a lower layer formed from aluminum and an upper layer formed from titanium nitride, the light-blocking shield layer having a fixed potential and being electrically connected to the fixed-potential-side capacitor electrode of the capacitor, the light-blocking shield layer having two edges running substantially in parallel with each other, one edge including an indented portion that recedes inward from the rest of the one edge; a first relay layer formed in a same layer above the substrate as the light-blocking shield layer and electrically connected to the pixel electrode; an insulating interlayer disposed below the first relay layer; a second relay layer formed in a different layer above the substrate than the light-blocking shield layer and the first relay layer with the second relay layer disposed on one side of the insulating interlayer, and the light-blocking shield layer and the first relay layer disposed on the other side of the insulating interlayer, the second relay layer being electrically connected to the pixel-potential-side capacitor electrode of the capacitor; and a contact hole electrically connecting the first relay layer to the second relay layer through a portion of the insulating interlayer that corresponds to the indented portion of the light-blocking shield layer so that the pixel electrode is electrically connected to the pixel-potential-side capacitor electrode of the capacitor, wherein the second relay layer covers the indented portion of the light-blocking shield layer in plan view to provide a light shield at the indented portion, the thin film transistor includes a semiconductor layer having a channel region that extends in a longitudinal direction and a channel adjacent region that further extends from the channel region in the longitudinal direction, and the scanning line includes a light-shielding part disposed at a side of the channel region.
