PURPOSE:To increase the luminance of a resin panel surface without causing luminance unevenness by reducing the thickness of a guide light. CONSTITUTION:A lamp 3 is disposed to correspond to approximately the halfway position of the vertical dimension of a resin panel 4, 4. Paint having calcium silicate mixed therein is applied to the inner surface of the resin panel 4 as a longitudinal strip, which becomes the coarser from a dense state the farther it is from the center of the plate along the vertical direction. The diffusion effects of the paint (calcium silicate) permit reduction in the thickness of a guide light 1, enabling the luminance of the surface of the resin panel 4 to be increased without causing luminance unevenness. |
