Abstract
A display device () includes a light source (), a light guide plate (), a display panel (), a panel driving unit that outputs, to the display panel (), a signal for controlling a transmittance of each pixel of the display panel (), and a light source driving unit (). Light can pass through a back surface of the light guide plate (), which is a surface opposed to the emission surface of the light guide plate (). The light source driving unit () drives the light source () based on the lighting control data. In a case where an image is displayed when the light source () is in ON state, the display panel () displays a color image, by controlling, pixel by pixel, a transmittance of light that passes from the light source () through the emission surface of the light guide plate. In a case where an image is displayed when the light source () is in OFF state, the display panel () displays a transmitted light image that includes a transmitting region through which the back of the display device () can be seen, by controlling, pixel by pixel, a transmittance of light that passes through the back surface of the light guide plate () and is incident on the display panel ().
