To provide a head-up display device which offers good visibility when viewed through polarized sunglasses and superior heat resistance.SOLUTION: A head-up display device of the present invention comprises: a display that emits projection light; at least one reflector for reflecting the projection light; a housing provided with an opening and configured to accommodate the display and the reflector therein; a cover member that covers the opening; and a polarizing plate disposed on the cover member on a side facing the inside of the housing. An in-plane retardation Re(550) of the cover member is 3000 nm or greater. The head-up display device of the present invention is configured such that a reflection angle of the projection light exiting from the housing through the opening is 30° or less, or 40° or greater with respect to a windshield.SELECTED DRAWING: Figure 1

    【課題】偏光サングラスを介して視認した場合の視認性に優れ、かつ、耐熱性に優れたヘッドアップディスプレイ装置を提供すること。【解決手段】本発明のヘッドアップディスプレイ装置は、投影光を出射する表示器と;投影光を反射する少なくとも1つの反射器と;開口部を有し、かつ、表示器および反射器を内部に収容する筐体と;開口部を覆うカバー部材と;カバー部材の筐体内部側に設けられた偏光板と;を有する。カバー部材の面内位相差Re(550)は3000nm以上であり、本発明のヘッドアップディスプレイ装置は、開口部を介して筐体から出射した投影光のフロントガラスに対する反射角が30°以下または40°以上となるよう構成されている。【選択図】図1
