A display device (10) includes a light source (19), a light guide plate (18), a display panel (11), a panel driving unit that outputs, to the display panel (11), a signal for controlling a transmittance of each pixel of the display panel (11), and a light source driving unit (16). Light can pass through a back surface of the light guide plate (18), which is a surface opposed to the emission surface of the light guide plate (18). The light source driving unit (16) drives the light source (19) based on the lighting control data. In a case where an image is displayed when the light source (19) is in ON state, the display panel (11) displays a color image, by controlling, pixel by pixel, a transmittance of light that passes from the light source (19) through the emission surface of the light guide plate. In a case where an image is displayed when the light source (19) is in OFF state, the display panel (11) displays a transmitted light image that includes a transmitting region through which the back of the display device (10) can be seen, by controlling, pixel by pixel, a transmittance of light that passes through the back surface of the light guide plate (18) and is incident on the display panel (11).
