ABSTRACT:
Substantially rectangular cut portions (11b) are formed at four substantially rectangular bent portions of a seal material (11) between an element substrate (10) and an opposing substrate (20), by removing the corners at the outer sides of the bent portions. Vertical electrically conducting members (13) are formed at the substantially triangular cut portion areas in order to allow electrical conduction between a signal input pad (18) on the element substrate and a transparent electrode (22) on the opposing substrate. The vertical electrically conducting members are virtually uniformly disposed along the outer periphery of the seal material. The vertical electrically conducting members act as supporting columns when the element substrate and the opposing substrate are being bonded together, and reduce the amount of deformation of the seal material when the opposing substrate contacts the seal material from one side during the bonding together of the substrates, so that the sealing performance of the seal material in the liquid crystal device is not affected, thereby making it possible to obtain a uniform cell thickness.
