DISPLAY AND VIEWING ANGLE CONTROL ELEMENT USED FOR SAME

摘要

It is an object to provide a display that can firmly shield light of entire visible wavelengths in the case where the display is 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 a projecting side polarizer (22). When a part of wavelength components (R, G) in visible wavelength light are incident on the liquid crystal cell (21) at a more than predetermined angle, the liquid crystal cell (21) gives the incident light a phase difference, so as to function as a first light shielding layer, which shields the light of the R and G components and does not make the light transmit through the projecting side polarizer (22). With respect to a retardation plate (4) and a polarizer (5), when the light transmitting through the first shielding layer is incident on the retardation plate (4) at a more than predetermined angle, the retardation plate (4) gives the incident light a phase difference, so as to function as an auxiliary light shielding layer, which does not make at least a part of a wavelength component (B) of the light transmit through the polarizer (5) and shields the light.
