摘要： It is an object to provide a display that can reliably shield visible light in the entire wavelength regions when viewed from an oblique direction and a viewing angle control element used for the display. A viewing angle control liquid crystal panel (2) is comprised of a liquid crystal cell (21) and an emission-side polarizing plate (22). When light having a part of wavelength components (R,G) in the visible wavelength regions enters at least at a predetermined angle, the liquid crystal cell (21) provides the incident light with a phase difference so as to function as a first light-shielding layer that shields the light of the R and G components not to pass through the emission-side polarizing plate (22). A retardation plate (4) and a polarizing plate (5) function as auxiliary light-shielding layers, more specifically, when the light that has passed through the first light-shielding layer enters at least at the predetermined angle, the retardation plate (4) provides the light with a phase difference so that at least light having a wavelength component (B) is shielded and thus not transmitted by the polarizing plate (5).

摘要： A composite retardation plate for use in a Twisted Nematic liquid crystal display device, at least includes: a first retardation film; and a second retardation film stacked on the first retardation film, the first retardation film being such that the first retardation film has a refractive index anisotropy which varies in thickness of the first retardation film so as to compensate for sequential variations in refractive index anisotropy of a liquid crystal layer included in the Twisted Nematic liquid crystal display device, the sequential variations being caused by a region which is approximately regarded as a region in which liquid crystal molecules hybridly orient during voltage application, and the second retardation film having a refractive index anisotropy for compensating for a residual refractive index anisotropy which remains after the compensation performed by the first retardation film. This provides a composite retardation plate which is capable of highly accurately compensating for a refractive index anisotropy which may cause a decrease in contrast of a TN liquid crystal display device due to a viewing angle.

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.
