In an electro-optical device, a relay electrode (first electrode) includes a conduction section that overlaps the projection portion of an inter-layer insulation film, and the conduction section is exposed from the surface (flat surface) of the inter-layer insulation film. An insulation film which has a film thickness thinner than the height of the projection portion is formed on the surface (flat surface) of the inter-layer insulation film, and a pixel electrode is electrically conducted to the conduction section through the opening of the insulation film. In this case, since the opening is shallow, a large uneven part is hardly generated on the surface of the pixel electrode.
