A liquid crystal display device is provided with a liquid crystal cell member, a light regulating member, a reflective polarizing member, and a control unit. The liquid crystal cell member has a first liquid crystal layer. An optical transmittance of the light regulating member changes with the application state of a second voltage. The reflective polarizing member transmits specific polarized light and reflects other polarized light. The polarization direction of light that is incident on the reflective polarizing member from the first liquid crystal layer is the same as the polarization direction of light transmitted by the reflective polarizing member. 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. |
