Claim:
1. A liquid crystal display device comprising: a liquid crystal cell member having a first liquid crystal layer in which an alignment of liquid crystal molecules is altered by application of a first voltage; a light regulating member disposed on a display surface side of the liquid crystal cell member, the light regulating member having an optical transmittance that is altered by an application state of a second voltage and being configured to scatter light; a reflective polarizing member disposed between the light regulating member and the first liquid crystal layer, the reflective polarizing member transmitting specific polarized light and reflecting other polarized light; and a control unit for altering the application state of the second voltage; wherein light incident on the reflective polarizing member from the first liquid crystal layer has a polarization direction identical to a polarization direction of light transmitted by the reflective polarizing member; and the control unit alters the application state of the second voltage in such a manner that the transmittance of the light regulating member when a backlight unit is on is higher than the transmittance of the light regulating member when the backlight unit is off.
