Abstract
A blind spot display device displays an image of blind spot blocked by an obstacle, and includes an incidence surface, a light guide member, a first reflecting surface closed to a display region, a second reflecting surface close to the blind spot, and multiple prism portions protruding toward the display region. An external environment light beam enters the incidence surface, reflects alternately on the first and second reflecting surface while passing through the light guide member, and emits toward the display region through the prism portions. Apexes of the prism portions are arranged in a three dimensional manner not along a plane.
