  1. 画像光を形成する画像表示装置と、
    前記画像表示装置から射出された前記画像光を入射させる投射光学系と、
    導光部と、前記導光部に画像光を入射させる光入射部と、前記導光部によって導かれた画像光を外部に射出させる光射出部とを有し、前記光射出部を介して前記画像光の観察を可能にする導光部材とを備え、
    前記導光部は、互いに平行に配置され全反射による導光を可能にする第1反射面と第2反射面とを有し、
    前記光入射部は、前記第1反射面に対して所定の角度をなす第3反射面を有し、
    前記光射出部は、前記第1反射面に対して所定の角度をなす第4反射面を有し、
    前記投射光学系は、前記第1反射面の平面と平行であり、前記第1反射面と前記第3反射面の交線に垂直な方向において、前記第3反射面の開口幅よりも広い射出開口幅を有する、虚像表示装置。
  2. 前記投射光学系の最も光射出側のレンズから前記導光部材の前記第1反射面までの距離が3mm以下である、請求項1に記載の虚像表示装置。
  3. 前記投射光学系の射出開口幅は、前記第1反射面と前記第3反射面との交線に平行な第1の方向よりも、前記第1反射面と平行で前記第1反射面と前記第3反射面との交線に垂直な第2の方向において、小さくなっている、請求項1及び2のいずれか一項に記載の虚像表示装置。
  4. 前記画像表示装置の有効サイズは、前記第1の方向よりも前記第2の方向において大きくなっている、請求項3に記載の虚像表示装置。
  5. 前記画像表示装置における第1部分領域から射出される第1画像光の前記導光部における反射回数と、導光に際して反射によって光路の折り返しが生じる閉じ込め方向に関して前記第1部分領域とは異なる第2部分領域から射出される第2画像光の前記導光部における反射回数とは、互いに異なる、請求項1から4までのいずれか一項に記載の虚像表示装置。
  6. 前記閉じ込め方向は、前記投射光学系を通る第1光軸と前記第3反射面の法線とを含む断面に平行な方向である、請求項5に記載の虚像表示装置。
  7. 前記第4反射面に、ハーフミラーが施されており、前記第4反射面に対向する透過面を有する楔状の光透過部材をさらに備える、請求項1から6までのいずれか一項に記載の虚像表示装置。
  8. 前記光透過部材は、前記第1反射面と第2反射面とに対してそれぞれ平行に配置される第1面と第2面とを有する、請求項7に記載の虚像表示装置。
  9. 前記導光部材は、射出成型によって独立して一体的に成型される、請求項1から8までのいずれか一項に記載の虚像表示装置。
  10. 前記導光部材は、熱重合型の樹脂材料によって成型される、請求項9に記載の虚像表示装置。
