Zusammenfassung:	To provide a display device capable of improving visibility.SOLUTION: A display device includes a light source for emitting a laser beam, a spatial phase modulator for displaying a calculator generation hologram 30 relating to a display image in a display region 31 having vertical and horizontal directions, and a control part for controlling the spatial phase modulator and generating the calculator generation hologram 30. The control part cuts out a pattern piece 43 of a rectangular predetermined region 42 which is a part of the calculator generation hologram 30 relating to the display image, and allows the spatial phase modulator to display an array pattern 40 generated by arraying a predetermined number of the pattern pieces 43 in the display region 31.SELECTED DRAWING: Figure 6 【課題】視認性を向上できる表示装置を提供する。【解決手段】本実施形態における表示装置は、レーザ光を出射する光源と、上下左右方向を有する表示領域３１に表示像に係る計算機生成ホログラム３０を表示する空間位相変調器と、空間位相変調器を制御し計算機生成ホログラム３０を生成させる制御部と、を備える。制御部は、表示像に係る計算機生成ホログラム３０の一部である矩形状の所定領域４２のパターン片４３を切り出し、パターン片４３を表示領域３１に所定数配列することにより生成した配列パターン４０を空間変調器に表示させる。【選択図】図６
