PROBLEM TO BE SOLVED: To provide a reflective screen which offers reduced crosstalk and capability to display high-quality 3D video images, and to provide a video image display system using the same.SOLUTION: A reflective screen 100 includes a lens layer 13 having a Fresnel-lens shaped back surface comprising a plurality of arrayed unit lenses 131, reflective layers 12 which are formed at least on lens surfaces 132 of the unit lenses 131 and almost specularly reflect light, and at least one optical function layer provided on an image source side of the lens layer 13. A sum of a value of pre-reflection retardation Re1 accumulated by video image light that enters the screen at an angle of 67° with respect to a normal line of the screen surface along a propagating direction thereof until the light reaches the reflective layer 12, and a value of post-reflection retardation Re2 accumulated by the video image light reflected by the reflective layer 12 along a propagating direction thereof while propagating in a direction substantially parallel with the normal line of the screen surface before exiting the screen shall be no more than 30 nm. |
