A display unit may include a display screen device to display contents formed by pixels based on image data, a parallax barrier including pixels forming slit parts and mask parts and arranged to display an autostereoscopic presentation in combination with the display screen device, and a sensor to sense a rotation of the display unit about an axis perpendicular to a surface of the display screen device from a reference rotational position. A pixel arrangement of the display screen device and a pixel arrangement of the parallax barrier may be rotated depending on the rotation of the display unit from the reference rotational position.
