Summary:To provide a video display device that can display a virtual image different in a focal length.SOLUTION: A video display device comprises: a display device that can display images; a liquid crystal element upon which light emitted from the display device is incident, and which can emit any of P polarized light and S polarized light selectively; a reflection type polarization member that reflects any one of the P polarization and S polarization emitted from the liquid crystal element, and transmits other light; and a reflection member that reflects the other light in the same direction as the one light reflected by the reflection type polarization member travels.SELECTED DRAWING: Figure 1 【課題】焦点距離が異なる虚像を表示可能な映像表示装置を提供する。【解決手段】映像表示装置は、画像を表示可能な表示装置と、前記表示装置から出射した光が入射され、Ｐ偏光及びＳ偏光のいずれかを選択的に出射可能な液晶素子と、前記液晶素子から出射された、Ｐ偏光及びＳ偏光のいずれか一方の光を反射し、他方の光を透過する反射型偏光部材と、前記他方の光を前記反射型偏光部材によって反射された前記一方の光が進む方向と同一方向に反射する反射部材と、を備える。【選択図】図１
