Abstract: A first substrate (10) of a liquid crystal display device (100) includes: an alignment film defining an initial alignment azimuthal direction (D), which is an alignment azimuthal direction of liquid crystal molecules (31) when no electric field is applied through a liquid crystal layer (30); a first electrode (11) and a second electrode (12) capable of producing a fringe electric field (FE) that aligns the liquid crystal molecules in an azimuthal direction that is different from the initial alignment azimuthal direction; and a third electrode (13) and a fourth electrode (14) capable of producing a lateral electric field that aligns the liquid crystal molecules in the initial alignment azimuthal direction.
