A method of manufacturing a luminous sheet according to the present invention enables a planar display unit radiating fluorescence upon irradiation of ultraviolet rays to be easily offered. A ability of radiating fluorescence is also increased. To this end, an ultraviolet-excited luminous material is applied and dried over a film-like base sheet 10 to form a light emitting layer 20, and a resin solution is applied and dried over an upper surface of the light-emitting layer to form a back layer 40. After thus forming the light-emitting layer 20 and the back layer 40 into a one-piece body, the base sheet 10 is peeled off from the light-emitting layer 20. The specific gravity of the fluorescent material is selected to be three times or more the specific gravity of the resin solution used for forming the ultraviolet-excited luminous material.
