Abstract
A liquid crystal display device (1) includes a first substrate (2), a second substrate (3) provided to face the first substrate (2), a liquid crystal layer (4) sandwiched between the first substrate (2) and the second substrate (3), a first polarizing plate (5) and a second polarizing plate (6) respectively provided on a side of the first substrate (2) and a side of the second substrate (3) which are opposed to sides to which the liquid crystal layer (4) is provided, and a common electrode (7) and a pixel electrode (9) provided to the liquid crystal layer (4) side of the first substrate (2). Alignment of liquid crystal molecules (4a) of the liquid crystal layer (4) is controlled by an electric field generated between the common electrode (7) and the pixel electrode (9). A polarizing layer (13) is provided on the liquid crystal layer (4) side of the second substrate (3) so as to be in contact with the liquid crystal layer (4). The polarizing layer (13) has a uniaxial absorption anisotropy, and serves as an alignment layer for regulating a direction of alignment of the liquid crystal molecules (4a).
