Abstract
A liquid crystal display device includes a pair of insulating substrates bonded to each other via a sealing material, and liquid crystal filled between a pair of the insulating substrates. A cell gap is formed so as to gradually increase from the center to an end of a display area at room temperature. According to this arrangement, it is possible to smooth out a difference in thermal expansion between the liquid crystal and the sealing material when an atmospheric temperature rises, and it is possible to prevent a cell gap from being too large in the center of the display area. Consequently, an irregular display color can be eliminated.
