A liquid-crystal display suitable for the optically compensated birefringence (OCB) display mode is used so as to simplify the voltage setting relating to display of each color by setting as follows. A liquid-crystal layer is oriented to bend alignment between a pair of substrates. A phase compensation plate is set for compensating a phase of the liquid-crystal layer outside of each of the substrates. And a retardation between the liquid-crystal and the phase compensation plates is set to a value 1/2 or less of the minimum wavelength of the light relating to display.
