Patent ID: 7098979

Claim:
An electro-optical device, comprising: a substrate; data lines; scanning lines extending in a direction crossing the data lines; switching elements to which a scanning signal is supplied through the scanning lines; pixel electrodes to which an image signal is supplied through the data lines and the switching elements; an alignment film formed on the pixel electrodes; the substrate having an image display area defined as an area to form the pixel electrodes and the switching elements, and a peripheral area defining the periphery of the image display area, the alignment film being formed in the image display area and the peripheral area, and convex portions being formed in the alignment film at least at a part of the peripheral area and extending in a direction substantially perpendicular to a rubbing direction of the alignment film; projected portions caused by the height of at least one of the data lines and the scanning lines being formed in the alignment film at a position directly adjacent to the display area, the convex portions being formed along a direction in which the scanning lines or the data lines extend and the convex portions including a plurality of linear convex portions which are formed along the direction in which the scanning lines or the data lines extend; and the pitch between the linear convex portions being equal to the pitch between the projected portions.
