Claims (1)
- 内面に回転放物面からなる反射面を有するリフレクタと、少なくとも発光部が平面と見なせる形状であると共に、前記平面に垂直に立てた法線に対して±90°以内の配光を有し、かつ、前記発光部が光学的に前記リフレクタの前記反射面を形成する前記回転放物面の焦点に位置するように配置された光源と、外部信号に応じて光の出力を変調可能な光変調素子と、前記発光部から出射され、前記リフレクタの前記反射面で反射された光を前記光変調素子に導く光学系と、前記光変調素子上の像をスクリーン上に拡大投写する投写光学系とを備えた投写型画像表示装置であって、
前記光学系を、前記リフレクタの出射面の前方に配置されたコンデンサレンズ及び前記コンデンサレンズの焦点位置に入射側開口部が位置するように配置されたロッドインテグレータ及び前記ロッドインテグレータの出射側開口部の像を前記光変調素子上に転写するリレー光学系か、又は前記リフレクタの出射面の前方に配置されたマイクロレンズの集合体であるレンズアレイ型インテグレータのいずれかにより構成し、かつ
前記リフレクタからの光の集光角が、前記リフレクタ及び光源を除く光学部材に共通の光軸であるシステム軸に対して略対称となるように、前記リフレクタの前記反射面の回転中心軸を前記システム軸に対して平行にシフトさせて配置したことを特徴とする投写型画像表示装置。
