A polarizing plate (14) is provided above TN liquid crystal panels (10), and a light scattering member (15) and a polarization separator (16) in the order mentioned above under the same panels (10). The polarization separator (16) is capable of permeating therethrough a linear polarization component, which is parallel to the surface of this paper out of the light entering an upper surface of the polarization separator (16), reflecting thereupon a linear polarization component thereof, which is perpendicular to the surface of the paper, and upwardly discharging a linear component, which is parallel to the surface of the paper out of the light entering a lower surface of the polarization separator. The external light entering a display is reflected on the polarization separator (16) and displayed brightly when the polarization separator (16) is off, and it is transmitted through the polarization separator, absorbed in the polarizing plate (14) and displayed darkly when the polarization separator (16) is on. The light from a light source (17) is transmitted through the polarization separator (16), absorbed in a polarizing plate (12) and displayed darkly when the polarization separator is off, and it is transmitted through the polarization separator (16) and a polarizing plate (14) as well and displayed brightly when the polarization separator is on.
