Abstract
Provided is a horizontal electric field mode reflective or transflective liquid crystal display device that achieves an increased reflectance. The liquid crystal display device sequentially includes: a first substrate; a first alignment layer; a liquid crystal layer containing liquid crystal molecules horizontally aligned with no voltage applied; a second alignment layer; and a second substrate including a pixel electrode and a common electrode, the liquid crystal display device further including a reflective layer disposed in at least part of a pixel at a position closer to a back surface than the first alignment layer, the liquid crystal layer, the second alignment layer, the pixel electrode, and the common electrode, at least one alignment layer of the first alignment layer or the second alignment layer having an azimuthal anchoring energy value of less than 1×10J/m.
