<P>PROBLEM TO BE SOLVED: To provide a surface illumination display which is a non-embedment type to permit use by being temporally installed mainly in a road surface, can be exchangeably mounted with an outer bag 14 and a contents, respectively, and makes the display clear. <P>SOLUTION: The self-luminous display plate device having waterproofness and the pressure resistance to provide protection against pressure due to passage of vehicles and persons is obtained by inserting into the outer bag 14 a pressure dispersion plate 13 superposed on an inner bag 12 in which a self-luminous plate 11 is covered and sealed. The device is easily stuck to the road surface and floor surface and is removed therefrom. The self-luminous plate 11 is supplied with electric power from a power source to light and flicker and therefore, the display contents can be recognized even at night and in the dark. The configuration to make the protection section of the outer bag 14, the light emitting section within the inner bag 12 and the display element independent by each section is employed, and therefore, the exchange and display change of the deteriorated protective material and the self-luminous plate 11 having degraded luminance are facilitated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
