PROBLEM TO BE SOLVED: To eliminate lowering of tansmittance due to a space in between sheet-like components in a lighting system, to efficiently emit light of a light source to a liquid crystal panel, and to facilitate assembling. SOLUTION: This lighting system has a light guide panel 2 for guiding the light from the light source, a reflecting sheet 1 for upwardly reflecting the light incident into the light guide panel 2, and a diffusion sheet 3 for diffusion- transmitting the light or a lens sheet 4 for convegence-transmitting the light, or both of them. They are formed of resin and are overlapped in layers to constitute the lighting system. |
