Abstract
An object of the technology of our invention is to solve a luminance defect viewed as a 'seam' or the like and to provide a liquid crystal display device having a screen for equally displaying an image. For example, when an exposing process is performed for one conductor layer or a dielectric layer, a total of four photomasks are used corresponding to four shot areas. A light insulation layer of a photomask used for the exposing process for patterning for example a signal line is formed so that it becomes a projection pattern of the signal line. The photomasks corresponding to adjacent shot areas are formed so that patterns of the light insulation layers of the boundary portion are engaged with each other on the plane.
