<p>The present invention provides a barrier element that can display white with high brightness and without variation in color tone during 2D display, and that can reduce crosstalk during 3D display. This barrier element is a barrier element (2) capable of forming a barrier pattern composed of a transparent section and a light-blocking section, the barrier element being disposed on the front or back surface of an image display element. The barrier element has: a first polarization control element (6); a liquid-crystal cell (5); and phase difference films (7, 8) in which the in-plane retardation Re (550) at a wavelength of 550 nm is -30 to 100 nm and the retardation Rth (550) in the thickness direction at a wavelength of 550 nm is 30 to 180 nm, the phase difference films being disposed between the first polarization control element and one of the surfaces of the liquid-crystal cell, and/or on the other surface of the liquid crystal cell.</p> |
