Abstract
A counter substrate of an electro-optical device incluedes a first lens, a first optical path length adjustment layer, a second lens, and a second optical path length adjustment layer. A first partition portion is provided between the first lens and the first optical path length adjustment layer. A second partition portion is provided between the first optical path length adjustment layer and the second lens. The second partition portion includes, across the entire second partition portion in an extending direction thereof, a plurality of first openings bored through the second partition portion. Thus, the ITO film can be formed in a region, where the first optical path length adjustment layer is covered by the second partition portion, under a condition similar to the condition for a region, where the first optical path length adjustment layer is not covered by the second partition portion.
