Abstract

PURPOSE: To improve the dispersion of luminance on a scattering body and to realize high-luminance display with uniform brightness by opening a part of a phosphor layer on a back surface side, irradiating a reflector with emitted light and irradiating the scattering body arranged on a display side with reflected light. CONSTITUTION: At least a part of the phosphor layer 5 on the back surface side is opened so as to emit the light L2 emitted from the inner wall surface of the layer 5 whose luminance is high. The reflector 2 formed to be curved on a display 1 side in the length direction of a fluorescent lamp 3 is irradiated with the light L2 , and the scattering body 1b arranged on the display 1 side is irradiated with the reflected light. By irradiating a position X2 on the lamp 3 where the light L1 transmitted through the layer 5 is weak with the reflected light L2 which is emitted from the inner wall surface of the layer 5, the dispersion of the luminance of the entire scattering body 1b is improved. Thus, a distance between a display board and the lamp 3 is shortened and the high- luminance display with uniform brightness is realized.
