Display and viewing angle control element used for same |
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).
