Abstract: Provided is a front reflection screen for a front projection display apparatus. The front reflection screen includes a reflection layer configured to reflect an incident light including an image light projected from a projector and an external light, and a tint layer disposed before the reflection layer and including light absorbing particles to block a portion of the incident light.
