Abstract: In order to reduce the number of processes for manufacturing spacers and to prevent quality degradation resulting from a cell gap, a spacer 115 in a semi-transmission area 12 is formed outside of a region of a bump layer 118B. Thus, it is made possible to manufacture the spacer in the transmission region 11 and the spacer outside of the region of the bump layer in the same process. Accordingly, the number of processes can be reduced. Moreover, it is made possible to determine the cell gap in the semi-transmission area 12 by a single element of a spacer. Accordingly, precision degradation of the cell gap, which results from the bump layer, can be prevented, and high display quality can be obtained.

Abstract: In order to realize a thinner liquid crystal display, supporting layers which would otherwise be respectively disposed in polarizing plates, each of which is at the side of a liquid crystal cell, are excluded. And retardation films, which are respectively disposed in the polarizers, each of which is at the side of the liquid crystal cell, are used with an additional function as protective layers of the polarizers. In order to reduce display unevenness, absorption axes of the polarizers are neither parallel nor perpendicular to slow axes respectively of the retardation films. Moreover, the absorption axes of the polarizers are neither parallel nor perpendicular to any one of the sides of the respective retardation films.
