<P>PROBLEM TO BE SOLVED: To provide an information display panel capable of producing an effect of indirect light leaking from the outer peripheral part of a character and a picture when a light source is lit, or an effect obtained by combining the indirect light with direct light. <P>SOLUTION: An information display panel 11 illuminated through a back surface by a light source 9 includes: a light transmissive support 1; a first reflection layer 2 and a first light-shielding layer 3 which are positioned in an observer 10 side of the information display panel 11 and are sequentially stacked in one surface side of the light transmissive support 1; and a second reflection layer 4 and a second light-shielding layer 5 which are positioned in a light source 9 side of the light transmissive support 1 and are sequentially stacked in the other surface side thereof, the first reflection layer 2 is arranged so as to have a size including a region corresponding to a position of an opening 5a provided in the second light-shielding layer 5 in an extending direction of the one surface and the other surface, the first light-shielding layer 3 is formed so as to be smaller than the first reflection layer 3 so that a part of the end of the first reflection layer 2 exposes in the observer 10 side, and the diffuse reflectance of the second reflection layer 4 is lower than that of the first reflection layer 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
