Description
車両用表示装置1は、図1に示すように、例えば自動車等の車両100に搭載されるヘッドアップディスプレイ装置である。車両用表示装置1は、車両100において、インストルメントパネル102の内側に配置され、被投影部材であるウインドシールド103に表示画像を投影する。ウインドシールド103は、入射する光の一部を反射し、残りを透過させる半透過性を有することから、車両100の前景を透過させながら、車両用表示装置1から出射された表示光Lを表示画像としてドライバDのアイポイントEPに向けて反射する。ドライバDは、車両100の乗員、特に運転者であり、ウインドシールド103によって反射された表示画像を虚像Sとして認識する。虚像Sは、ドライバDに対してウインドシールド103よりも前方に認識される。本実施形態の車両用表示装置1は、図2の(A)に示すように、筐体2と、2つの反射ミラー3と、バックライトユニット5と、制御部7とを含んで構成される。
