To extend the range of distance (between a display screen and the eye of a viewer) with which the viewer can see 3D images with the naked eye and to reduce power consumption. A parallax barrier in a shutter panel is controlled to be arranged optimally in accordance with the distance between the viewer and a display panel. Specifically, an optimal parallax barrier is formed as appropriate by selectively switching a light-transmitting state and a light-shielding state of a plurality of optical shutter regions and a display element unit of pixels depending on a retention state. The retention state is realized in such a manner that at least one of electrodes between which a liquid crystal layer is sandwiched is connected to a transistor including a semiconductor layer containing an oxide semiconductor and the transistor is turned off.
