A liquid crystal display device including a pair of substrates, a liquid crystal layer sealed between the pair of substrates, and a seal member for sealing peripheries of the substrates. The seal member may be of rectangular shape in plan view, thereby defining two end parts and two side parts, with one of the end parts including an injection port. The device may also include one or more structures formed near the seal member for slowing an injection speed of a liquid crystal when it is injected into a space between the substrates. The structures may be formed integrally with the seal member. In certain embodiments, a thickness of the liquid crystal layer in a vicinity of the seal member is less than that of the liquid crystal layer in a display region, due to the structure. Also, in certain embodiments, the structures are generally L-shaped, in plan view.
