Abstract:
1. An electro-optical device comprising: a substrate; a plurality of data lines and a plurality of scanning lines provided on the substrate and crossing each other; a plurality of pixel electrodes provided on the substrate at a plurality of pixels, the plurality of pixels being defined in association with intersections of the plurality of data lines and the plurality of scanning lines and constituting a display region on the substrate; a plurality of transistors that controls switching of the plurality of pixel electrodes, the plurality of transistors being provided on the substrate in non-aperture regions separating aperture regions of the plurality of pixels each other, each of the plurality of transistors being formed along a first direction in the display region; and a plurality of light-blocking portions provided on the substrate, the plurality of light-blocking portions being formed in a layer below the plurality of pixel electrodes via an inter-layer insulating film and above the plurality of transistors so as to define the non-aperture regions at least partially, each of the plurality of light-blocking portions having an overlapping portion, one of the overlapping portions including a portion that overlaps an associated one of the plurality of transistors along the first direction when viewed in plan on the substrate and being wider than the associated one of the plurality of transistors along a second direction crossing the first direction; wherein: an associated one of the plurality of pixel electrodes is electrically connected to the associated one of the plurality of transistors via a contact hole formed through the inter-layer insulating film; the one of the overlapping portions further including: a width of the second portion being wider than a width of the first portion in the second direction; and the contact hole overlapping the second portion in plan view.
