PROBLEM TO BE SOLVED: To provide a reflective screen which allows simplification of the configuration and improvement in the convenience, while suppressing reduction in contrast due to the influence of external light. SOLUTION: In an external light removing sheet 3 constituting a reflective screen 1, a plurality of total reflecting surfaces 321 which are turned facing upward and a totally reflecting external light R22, traveling inward from a light-incidence surface 31 and a plurality of absorbing surfaces 322, turned downward and absorbing external light which is totally reflected by the total reflecting surfaces 321 are formed alternately along a vertical direction, on a surface 32 facing a reflecting surface 2A of the screen body 2.
