Zusammenfassung:	PURPOSE: To improve the uniformity of light emission by making light in weight of a light transmission plate and simultaneously preventing black lines from occurring on a light emitting plane. CONSTITUTION: Concerning the light transmission plate system for which light is made incident from one end face 9 of a light transmission plate 1 and the side of a light emitting plane 2 is emitted through the inside of the light transmission plate 1, a parallel part 13 is provided while forming a reflecting plane 13 almost parallel to the light emitting plane 2 so that the thickness of the light transmission plate 1 can be made equal just for prescribed width (a) oppositely from the terminal part of the light transmission plate 1 on the side of a light source 8 to the light source 8, and an inclined part 14 is provided while inclining the reflecting plane 3 toward the light emitting plane 2 so that the thickness of the light transmission plate 1 can be gradually reduced from the parallel part 13 to the terminal part on the opposite side of the light source 8.
