Abstract
A reflector is used in a display device and is disposed parallel to a predetermined plane, and has plural unit reflecting portions each having a reflection face for reflecting incident light in a direction different from that of regular reflection light of the predetermined plane. Further, the distance between a first tangential plane abutting on a first reflection face arranged in an arbitrarily extracted first unit reflecting portion at a reference point arranged in an arbitrary position on the first reflection face, and a second tangential plane abutting on a second reflection face arranged in a second unit reflecting portion adjacent to the first unit reflecting portion in parallel with the first tangential plane is preferably half or more of a coherent length of the incident light.
