A three-dimensional-image display device capable of displaying an image with high brightness while suppressing power consumption is provided. The display device is provided with an image display portion where a plurality of pixels is provided in a pixel portion, a light-shielding portion including a first shutter and a second shutter, and a control portion for controlling the transmittances of the first shutter and the second shutter in synchronization with display of an image for the right eye or an image for the left eye in the pixel portion. The pixel includes a switching transistor for controlling an input of an image signal to the pixel, a light emitting element, a driving transistor for controlling the value of a current supplied to the light emitting element in accordance with the image signal, and a current controlling transistor for controlling whether or not the current is supplied to the light emitting element. |
