パターンを有する透明板体と、この透明板体の裏
面側から前面側に投光し上記ホログラムパターン
を立体像と浮び上がらせる光源とからなり、この
光源からホログラムパターンを介して目視者の視
点を結ぶ入射角度αを１２０°≦α≦１５５°の
範囲に設定し、上記光源のホログラムパターンに
対する入射角の水平成分βを−４５°≦β≦４５
°の範囲に設定したことを特徴とする表示装置。 The light source consists of a transparent plate having a hologram pattern formed by a laser beam on its back surface, and a light source that projects light from the back side of the transparent plate to the front side to make the hologram pattern appear as a three-dimensional image. The incident angle α connecting the viewer's viewpoint through the hologram pattern is set in the range of 120°≦α≦155°, and the horizontal component β of the incident angle of the light source to the hologram pattern is set as -45°≦β≦45.
A display device characterized in that the display device is set within a range of °.
