<p><P>PROBLEM TO BE SOLVED: To provide a reflective screen capable of improving a shielding property and an absorbing property of external light. <P>SOLUTION: In a reflective screen, multiple cell elements 6 each having a three-dimensional structure are arranged in line in a lateral direction and a longitudinal direction so that a screen surface is configured. The cell element 6 has a three-dimensional structure having a cut end surface obtained by cutting diagonally a columnar body as a reflective surface 8 and an outer peripheral side wall surface 9 as an external light absorption surface. A cross section of a cell row which is a row of the multiple cells 6 arranged in line in the longitudinal direction has a saw-tooth shape formed of the cut end surface (reflective surface 8) and the side wall surface 9. The multiple cell elements are arranged such that adjacent cell rows have a phase difference having a length shorter than the height of the cell element 6. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
