Abstract
A liquid crystal display device comprising a liquid crystal panel, in which there are formed on opposing faces of a pair of substrates a light shield film or a wiring which do not transmit light, a seal member is applied onto the opposing faces for forming an injection port for liquid crystal, and the pair of substrates are adhered together. A sealing material for sealing the injection port is resin that is curable by ultraviolet light or by visible radiation. At least one of the substrates is formed with a transmitting portion through which the ultraviolet light or visible radiation can transmit at a portion in the proximity of the injection port of the light shield film or wiring. Even if sealing material has penetrated between a pair of substrates, it can be cured by irradiated ultraviolet light or visible radiation by the provision of a transmitting portion, and dispersion of uncured sealing material into liquid crystal can be prevented.
