PURPOSE:To provide an inexpensive planar light-emitting panel unit which can uniformly light a wide area. CONSTITUTION:A panel unit has superposed body structure where panels (12-2 and 12-3) one side each of which has the shape of irregularity having a predetermined distribution and the other side each of which consists of a transparent plane are combined, and the fellow one side is junctioned with the other. The image of a filter can be displayed by selecting the number of the gaps of the superposed body structure, that is, the number of irregularities and also, making the light vertically permeate a panel face permeating it through an acrylic resin plate (12-5) having an image drawn. |
