Abstract

An electro-optical device of the present embodiment includes a pair of substrates, first opening components that stipulate sizes and positions of opening sections of pixels in one of the pair of substrates, and second opening components (microlenses) that stipulate sizes and positions of opening sections of the pixels in the other of the pair of substrates. Positions of the second opening components (microlenses) of the other substrate are corrected with positions of the first opening components of the one substrate set as references, so as to gradually become more shifted in a direction that runs from a core of a pixel region, in which a plurality of pixels are arranged, toward an edge section of the pixel region, in accordance with separation from a core side of the pixel region.
