Claim Text:
1. A display device comprising: a display panel including a plurality of pixels; a shutter panel including a driver circuit, a liquid crystal, and light-transmitting electrodes provided in a striped manner; and a positional data detector configured to detect a positional data of a viewer, wherein the shutter panel is provided over a display surface side of the display panel, wherein a width of one of the light-transmitting electrodes is smaller than that of one of the plurality of pixels, wherein the driver circuit is configured to selectively output signals for forming a parallax barrier to the light-transmitting electrodes, wherein the parallax barrier is capable of changing its shape in accordance with the detected positional data, wherein the shutter panel further comprises an electrode, wherein the liquid crystal is interposed between the light-transmitting electrodes and the electrode, wherein the positional data detector comprises a first ultrasonic wave receiver and a second ultrasonic wave receiver, and an ultrasonic wave transmitter between the first ultrasonic wave receiver and the second ultrasonic wave receiver, so that the positional data detector recognizes an angle and a distance between the display device and the viewer, and wherein the shutter panel further comprises transistors each including an oxide semiconductor layer served as a channel.
