摘要: The present invention provides a reflex-type screen which is wound up by a winding shaft to be retracted and is unwound from the winding shaft in use. The reflex-type screen comprises a reflection layer which reflects an incident light, a transparent surface protective layer provided on a first surface of the reflection layer, and a back surface protective layer provided on a second surface of the reflection layer, wherein as between the surface protective layer and the back surface protective layer, the one that has a higher loop stiffness value, faces inward when the reflex-type screen is wound up by the shaft.
