With the liquid crystal layer 50 being driven, the liquid crystal molecules LC behave (vibrates) as described above, and a flow of the liquid crystal molecules LC occurs in the oblique deposition direction (one-axis direction) near the interface between the liquid crystal layer 50 and the alignment film 18 and 24 as illustrated with the dashed or solid arrow illustrated in FIG. 4. If the liquid crystal layer 50 contains anion (?)based or cation (+)based ionic impurities, the ionic impurities may move along the flow of the liquid crystal molecules LC toward the corner portion at the lower left or the corner portion at the upper right in the display region E1, and be unevenly distributed (agglomerate). When the insulation resistance of the liquid crystal layer 50 in a pixel P located at a corner portion decreases due to uneven distribution of the ionic impurities, this leads to a decrease in drive potential at the pixel P. This results, for example, in display unevenness in which light leak occurs as illustrated in FIG. 4 or a burn-in phenomenon due to energization. In particular, when an inorganic alignment film is used for the alignment film 18 and 24, the inorganic alignment film is more likely to absorb ionic impurities, and hence, stain or unevenness of display or burn-in phenomenon more stands out due to uneven distribution of the ionic impurities as compared with an organic alignment film. Note that the location of stain or unevenness of display or burn-in occurring due to uneven distribution of ionic impurities is not limited to the corner portion at the lower left or the corner portion at the upper right as illustrated in FIG. 4. The location of occurrence varies depending on an alignment direction of the liquid crystal molecules LC or paths through which ionic impurities enter or states of diffusion as described above.
