Abstract:
1. A multi-display apparatus, comprising: flat panel display devices having adjacent sides connected to each other; an optical path changing unit having at least one inclined surface symmetrical to a boundary surface of the flat panel display devices and shifting light emitted from the flat panel display devices toward a boundary surface between the flat panel display devices to display an image without a non-display area, at least one of the inclined surfaces being an exit surface where light leaves the optical path changing unit; and a polarizing film adjacent to the optical path changing unit and having a smaller refractive index than a refractive index of the optical path changing unit, wherein the light passes through the polarizing film, is incident on the optical path changing unit and is refracted, and at least one of the inclined surfaces of the optical path changing unit refracts the previously refracted light as the light is emitted from the inclined exit surface of the optical path changing unit, and wherein the light is output from the inclined exit surface of the optical path changing unit to be perpendicular with respect to a light-entering surface of the optical path changing unit and horizontally shifted toward the boundary surface.
