To provide a directional backlit type display device.SOLUTION: A directional backlit type display device comprises a backlight including a light source module and a reflective narrow-angle diffuser including an array of a plurality of micro-curved mirrors reflecting light and uniformly diffusing the light with a narrow diffusion angle. A backlit type display panel is configured on a projecting path where the reflective narrow-angle diffuser reflects the light to an observer, and the backlit type display panel displays an image projected to an eye box of the observer by the reflected light. At least one of the micro-curved mirrors of the reflective narrow-angle diffuser corresponding to each pixel of the image uniformly diffuses the light of each pixel to the eye box of the observer, and diffusion areas of all pixels on the backlit type display panel superimpose on the eye box of the observer.SELECTED DRAWING: Figure 11

    【課題】指向性バックライト型表示デバイスを提供すること。【解決手段】指向性バックライト型表示デバイスは、光源モジュールを備えるバックライトと、光を反射し、狭拡散角で光を均一に拡散する複数の微小湾曲鏡アレイを備える反射狭角拡散器とを備え、バックライト型表示パネルは、反射狭角拡散器が光を観察者に反射する投射路上に構成され、バックライト型表示パネルは、反射光によって観察者のアイ・ボックスに投射される画像を表示し、画像の各画素に対応する反射狭角拡散器の微小湾曲鏡の少なくとも1つは、各画素の光を観察者のアイ・ボックスに均一に拡散し、バックライト型表示パネル上の全ての画素の拡散領域は、観察者のアイ・ボックス上に重ねられる。【選択図】図11
