편광 선글라스를 통해 시인한 경우의 시인성이 우수하고, 또한, 내열성이 우수한 헤드업 디스플레이 장치(100)가 제공된다. 본 발명의 헤드업 디스플레이 장치(100)는 투영광을 출사하는 표시기(10)와; 투영광을 반사하는 적어도 1개의 반사기(20)와; 개구부(32)를 갖고, 또한, 표시기(10) 및 반사기(20)를 내부에 수용하는 하우징(30)과; 개구부(32)를 덮는 커버 부재(40)와; 커버 부재(40)의 하우징 내부측에 설치된, 커버 부재(40)측으로부터 순서대로 위상차층(52)과 편광자(54)를 포함하는 위상차층 부착 편광판(50);을 갖는다. 위상차층(52)의 면내 위상차 Re(550)는 3000nm 이상이며, 본 발명의 헤드업 디스플레이 장치(100)는 개구부(32)를 통해 하우징으로부터 출사한 투영광의 프론트 유리에 대한 반사각이 30° 이하 또는 40° 이상이 되도록 구성되어 있다.

    Provided is a head-up display apparatus (100) having excellent visibility during viewing via polarization sunglasses, and having excellent heat resistance. The head-up display apparatus (100) according to the present invention comprises: a display device (10) which emits projection light; at least one reflection device (20) which reflects the projection light; a casing (30) which has an opening portion (32) and in which the display device (10) and the reflection device (20) are accommodated; a cover member (40) which covers the opening portion (32); and a retardation-layer-provided polarization plate (50) which is provided on the casing interior side of the cover member (40) and which has a retardation layer (52) and a polarizer (54) in order from the cover member (40) side. The in-plane phase difference Re (550) of the retardation layer (52) is at least 3000 nm. The head-up display apparatus (100) according to the present invention is configured in such a way that the angle of reflection of the projection light emitted from the casing through the opening portion (32) is at most 30°, or is at least 40° with respect to a windshield.
