An electro-optical device includes a first substrate, a second substrate, an adhesive agent between the first and second substrates, and an inorganic film. The adhesive agent has a first face stuck to the first substrate, a second face stuck to the second substrate, and a third face between the first and second faces. The inorganic film covers the third face on one side of the electro-optical device, a region of the first substrate between the first face and a side of the first substrate on the one side, and a region of the second substrate between the second face and a side of the second substrate on the one side. A distance between the first substrate and the second substrate is less than a distance between the first face and the side of the first substrate, and a distance between the second face and the side of the second substrate.

Electro-optical device and electronic apparatus

An electro-optical device comprises an element substrate, a counter substrate, and an inorganic film. The counter substrate is arranged so as to face the element substrate. The seal material is arranged between the element substrate and the counter substrate so as to join the element substrate and the counter substrate. The inorganic film covers a side face of the seal material, a peripheral region of the element substrate between the side face of the seal material and a side of the element substrate, and a peripheral region of the counter substrate between the side face of the seal material and a side of the counter substrate.

An electro-optical device includes an element substrate, a counter substrate arranged so as to face the element substrate through a seal material, in which the element substrate, the counter substrate, and the seal material are arranged so that a ratio of a length from a side face of each of the element substrate and the counter substrate to the seal material to a length of an interval between the element substrate and the counter substrate becomes from 50 to 300, and a barrier film is provided so as to cover the seal material and at least a part of side faces of the element substrate and the counter substrate.

To make it difficult to view streak unevenness in alignment generated at the boundary of alignment layers even when an alignment-layer material is applied onto a color-filter substrate several times to form an alignment layer. When an alignment-layer material is applied onto a color-filter substratehaving color filters (R, G, and B) on the surface with a droplet discharge headto form an alignment-layer train, the lateral front end Lof the trainis formed on the color filter (B) displaying blue. When the alignment-layer material is then applied to the following alignment-layer application train to form an alignment-layer train, the lateral rear end Lof the trainis overlapped with the lateral front end Lof the preceding alignment-layer trainto form an overlapped portion. Since the overlapped portionis formed on the color filter (B) displaying blue which has the lowest visibility of the three primary colors of light, streak unevenness in alignment generated at the boundary is difficult to view from the exterior.
