Provided are a light storable panel which can maintain a brightness high enough to be used as a guide display or directory display over a long period of time in a dark place and which exhibits an improved durability for outdoor use and a manufacturing method of the light storable panel. In the light storable panel (1) which is formed of a resin (3) containing light storable emitters (2), the light storable emitters (2) contained in the resin (3) are unevenly distributed on the panel front surface side, and accordingly, for the same amount of light storable emitters contained in the resin, the brightness is higher than that of a conventional light storable panel in which light storable emitters are evenly distributed in a resin, and no fine cracks occur in an interface between layers when the panel made of laminated layers is used outdoors. The liquid resin (3) in which the particles of the light storable emitters (2) are mixed is introduced and left in a panel forming mold so that the precipitation of the particles of the light storable emitters (2) occurs, whereby the resin (3) is set. Therefore, the uneven distribution of the light storable emitters (2) can be easily achieved by the precipitation of the light storable emitters (2).

Abrégé

Disclosed is a method for manufacturing phosphorescent light-emitting body particles with excellent water resistance and with uniform particle size and phosphor distribution. On a temporary retaining member, (1) a mask having periodically arranged holes is mounted, and multiple mixture layers (A) are formed by screen printing a mixture of glass fine particles and a resin adhesive agent; (2) before the resin adhesive agent hardens, phosphor particles and glass particles are spread on the mixture layers (A), forming a phosphor layer (B) on the mixture layers (A); (3) the mask used in step (1) is aligned and mounted on the phosphor layer (B) and a mixture layer (A) is formed by screen printing a mixture of glass fine particles and a resin adhesive agent; (4) by repeating step (2) and step (3) as needed, a granular laminate is formed with three layers or five or more layers wherein the mixture layer (A) and the phosphor layer (B) are stacked alternately; and (5) glass-coated phosphorescent light-emitting body particles are manufactured by firing the granular laminate.
