- 表示光を発する液晶表示素子を有し、前記表示光を透明反射部材に投影して映像表示を行うヘッドアップディスプレイ装置であって、
前記液晶表示素子から前記透明反射部材へと至る前記表示光の光路中に、可視光を透過し、赤外光を反射させる透過反射部材と、一方の偏光を反射して他方の偏光を透過する反射型偏光分離性を有した偏光光学部材と、が前記表示光を透過するように配置され、
前記表示光の光路に対して、前記透過反射部材は垂直、および、前記偏光光学部材の偏光分離層は傾斜して配置され、
傾斜して配置された前記偏光分離層は、入光した太陽光を偏光分離して、光路を逆に進むように反射することを防止し、
前記透明反射部材が表示する映像の偏光方向が水平以外であり、
前記偏光光学部材が固有の偏光軸を有した反射型偏光板からなり、
前記偏光光学部材の前記偏光分離層が前記表示光の偏光方向と平行、および、直交方向に多軸回転して配置されていることを特徴とするヘッドアップディスプレイ装置。 - 前記偏光光学部材が平板状のガラス基板の一方の面に、150nm以下の間隔をもって所定の方向に延在する導電体からなるワイヤグリッド層を有していて、前記導電体間に樹脂が充填されていることを特徴とする請求項1に記載のヘッドアップディスプレイ装置。
