Abstract:
1. A display device comprising: a display panel; and a shutter panel comprising a first liquid crystal element and a second liquid crystal element adjacent to the first liquid crystal element, a sensor configured to detect a distance between the display device and a viewer by an infrared sensor and a gyro sensor, wherein in a first display state, a first light-shielding region and a first light-transmitting region are formed in the shutter panel by the first liquid crystal element and the second liquid crystal element, and light from the display panel is emitted through the first light-transmitting region, wherein in a second display state, a second light-shielding region larger than the first light-shielding region and a second light-transmitting region smaller than the first light-transmitting region are formed in the shutter panel by the first liquid crystal element and the second liquid crystal element, and light from the display panel is emitted through the second light-transmitting region, wherein the shutter panel is positioned in a direction of the light from the display panel, and wherein one of the first display state and the second display state is selected in accordance with the distance detected by the sensor.
