<P>PROBLEM TO BE SOLVED: To provide a double-sided light emitting panel with a light irradiation surface having no fluctuation in brightness and ensuring even illumination by enabling the light irradiation surface formed by both side surfaces of a light guide plate to illuminate uniformly. <P>SOLUTION: This double-sided light emitting panel is formed by a light transmitting substrate member, and a lot of light reflecting means are formed as reflecting dots (14, 16) on the light irradiation surface of both side surfaces of the substrate by dot printing. The reflecting dot formed on one surface side and the reflecting dot formed on the other surface side are formed while shifting from each other so that their formation positions do not overlap with each other. Irradiating light from a light source is reflected by utilizing each of the reflecting dots, and the reflected irradiating light is transmitted from the facing light irradiation surface side to emit light from both sides. <P>COPYRIGHT: (C)2011,JPO&INPIT |
