Abstract
A liquid crystal device includes an elemental substrate provided with a silicon oxide alignment layer on the front surface side thereof. Silanol groups of the alignment layer are bound to an organic silane polymer layer by silane coupling treatment. The silane coupling treatment also forms an organic silane polymer layer on the rear surface side of the elemental substrate. This organic silane polymer layer is a layer having a higher hydrophilicity than the organic silane polymer layer. A light-transmitting plate bonded to the rear surface side of elemental substrate with an adhesive layer is thus unlikely to separate.
