Abstract: A display device includes a circuit substrate that is formed of a plurality of layers including a light control element; a counter substrate that faces a surface of the circuit substrate on which the light control element is disposed, with a gap therebetween; a seal that is disposed between the circuit substrate and the counter substrate to surround the light control element; and a filler with which a sealed space surrounded by at least the circuit substrate, the counter substrate, and a sealing surface of the seal is filled. The sealing surface includes internal angle corner surfaces formed by an inner surface of the seal, and a convex surface formed adjacent to the corner surfaces from at least one of the circuit substrate, the counter substrate, and the seal.
