Description
図1から図10を参照して、実施形態について説明する。本実施形態は、車両用表示装置に関する。図1は、実施形態に係る車両用表示装置の概略構成図、図2は、実施形態に係るホログラムによる光の回折を説明する図、図3は、ウインドシールドによる反射光を説明する図、図4は、実施形態に係る投射装置の構成を示す図、図5は、実施形態の規制部による拡散角度の規制について説明する図、図6は、ウインドシールドの上部において反射される反射光の説明図、図7は、ホログラムの上部において回折される回折光の説明図、図8は、ウインドシールドの下部において反射される反射光の説明図、図9は、ホログラムの下部において回折される回折光の説明図、図10は、車幅方向において反射光を逸らす構成を示す図である。
画像表示装置4として、レーザスキャナとは異なる装置が用いられてもよい。例えば、画像表示装置4として、TFT−LCD(Thin Film Transistor−Liquid Crystal Display)、有機ELディスプレイ、LEDアレイディスプレイなどが用いられてもよい。この場合、画像表示装置4の前面に拡散角度を規制するための規制部5が設けられる。規制部5として用いられる光学素子としては、レンズアレイ、ルーバー、格子フィルター(ストライプ)などが挙げられる。
