Abstract
According to an embodiment, the display unit includes pixels, each pixel includes sub-pixels having different colors, arranged in a matrix in a first direction and in a second direction substantially orthogonal to the first direction. The light beam controller faces the display unit, extends in a third direction making an angle smaller than 90° with the second direction, includes light beam control elements periodically arranged at a first pitch in the first direction and at a second pitch in the second direction, and can control direction of light beams from the display unit. The first and second pitches make a substantially equilateral triangle by joining the nearest same-color sub-pixels. When 's' represents the number of the sub-pixels included in the pixels along the first direction, the first pitch is 5/s or greater of a third pitch of each pixel.
