摘要： A liquid crystal device includes: an element substrate; a counter substrate disposed opposite to the element substrate; a sealing material disposed between the element substrate and the counter substrate; and a liquid crystal layer disposed on an inner side of the sealing material and containing liquid crystal. The element substrate includes an alignment film configured to align the liquid crystal and an ion-adsorbing first adsorption film disposed in contact with the sealing material. The alignment film includes a first vapor-deposited film and a second vapor-deposited film disposed between the first vapor-deposited film and the liquid crystal layer. The second vapor-deposited film and the first adsorption film include a column of which a long axis direction intersects a thickness direction of the liquid crystal layer. A thickness of the first adsorption film is thicker than a thickness of the second vapor-deposited film.
