    摘要: A liquid crystal display device includes a reflective liquid crystal panel (20) having a liquid crystal panel polarization plate (22), a polarization plate (32) provided on a front surface side of the polarization plate (22) with its absorption axis in parallel with an absorption axis of the polarization plate (22), and a negative C plate (31) provided between the liquid crystal panel polarization plate (22) and the polarization plate (32). The negative C plate (31) sets a direction in which viewing limitation is carried out. Thus, it is possible to provide the liquid crystal display device in which a viewing angle can be narrowed by freely setting, in the reflective liquid crystal panel, the direction in which the viewing limitation should be carried out.
