Abstract
A liquid crystal display element which comprises a pair of substrates facing each other forming a cell gap therebetween and a sealing paste for bonding the pair of substrates and defining the cell between the substrates. The sealing paste is arranged to have an opening at a side edge of the cell for forming an injection port for injecting a liquid crystal in the cell. The port is sealed after the liquid crystal is injected in the cell. The display element further comprises a sealing member inserted onto the side edge of the cell at the position of the injection port. A clogging paste for covering and sealing the injection port is held within said sealing member.
