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.

摘要： A negative C plate (31) is arranged to be between a polarizing plate (32) and a reflective liquid crystal panel (20). A retardation of the negative C plate (31) is set so that a combination of the negative C plate (31) and the liquid crystal panel (20) generates a phase difference of “nλ/4+λ/8 (n is 0, or a positive or negative integer)” for a one-way light path with respect to linearly-polarized light entering into the liquid crystal display device. This makes it possible to provide, at low cost, a liquid crystal display device whose viewing angle can be narrowed by arbitrarily setting a direction in which visibility is limited.

摘要： There are provided a display that can block light so that a display on an image display device is invisible from a wide range of view angles in an oblique direction, and a view angle control element employed therein. In a narrow view angle state, a view angle control liquid crystal panel (2) prevents light in a predetermined wavelength region that has been incident at a polar angle of φH or more from being transmitted through a polarizing plate (22) by using a phase difference imparted by a liquid crystal cell (21). In the narrow view angle state, a view angle control liquid crystal panel (3) prevents light that has been incident at a polar angle of φL or more, among light that has been transmitted through the polarizing plate (22), from being transmitted through a polarizing plate (32) by using a phase difference imparted by a liquid crystal cell (31). Consequently, light forming a polar angle of φL or more is blocked as a whole, which allows the narrow view angle state to cover a wide range.
