The LED unit (10) has a left-eye LED array (6) and a right-eye LED array (8), each including plural LEDs (4) aligned in a column. The left-eye LED array (6) displays a left-eye image through an afterimage effect produced by displaying, while rotating, columns of pixel groups constituting the left-eye image. The right-eye LED array 8 displays a right-eye image through an afterimage effect produced by displaying, while rotating, columns of pixel groups constituting the right-eye image. Light from the left-eye image enters the left eye of a viewer, whereas light from the right-eye image enters the right eye. The viewer recognizes a three dimensional image in a range of 360° around the viewer based on binocular parallax.
