Abstract
A filtering panel includes a molding layer part; a pattern layer part having an incident surface through which light emitted from a light source and viewing light transmitted to an observer enter, and an accommodation surface which is the reverse surface of the incident surface, wherein the molding layer part is stacked on the incident surface so as to be adjacent thereto, and the pattern layer part adjusts the optical paths of the emitted light and the viewing light; and a filtering layer part formed on a lower incident surface of the pattern layer part having the incident surface of the viewing light that enters from a lower region below a horizontal reference line, wherein the reflectivity of the visible light in the viewing light incident on the lower region is made greater than that of an upper region above the reference line by means of mirror reflection.
