Abstract:
1. A liquid crystal display device, comprising: a first substrate; a second substrate; a liquid crystal layer sandwiched between the first substrate and the second substrate; a first polarization plate placed on a side opposite to a side of the first substrate on which the liquid crystal layer is placed; a second polarization plate placed on a side opposite to a side of the second substrate on which the liquid crystal layer is placed; and a pixel electrode and a common electrode which are provided on the side of the second substrate on which the liquid crystal layer is placed, wherein: one of the pixel electrode and the common electrode is interdigital in shape and the other of the pixel electrode and the common electrode is planar in shape; the liquid crystal layer has flexoelectric coefficients e the pixel electrode and the common electrode are laminated via an insulating layer; the one of the pixel electrode and the common electrode is closer to the liquid crystal layer than the other of the pixel electrode and the common electrode; and the liquid crystal display device further comprises a dielectric cap having a permittivity lower than a permittivity of the liquid crystal layer, the dielectric cap being formed between the liquid crystal layer and the one of the pixel electrode and the common electrode which is interdigital in shape so as to cover an outer peripheral portion of at least one tooth of the one of the pixel electrode and the common electrode and not to cover a center of a gap between adjacent teeth of the one of the pixel electrode and the common electrode.
