    Abstract: In an electro-optical device, one surface side of a first substrate is provided with a wall portion covering a light-shielding body with an edge overlapping a pixel electrode in a plan view and a transmissive body located in a region surrounded by the wall portion. A cavity is provided between a side surface of the wall portion and the transmissive body. The cavity has a refractive index of 1, and thus, there is a significant difference in refractive index at a boundary surface between the transmissive body and the cavity. Therefore, even in a case where light travels to advance obliquely toward the wall portion, the boundary surface between the transmissive body and the cavity reflects the light toward the transmissive body with high reflection efficiency, and contributes to display. The cavity is a vacuum.
