Surface-emitting device and liquid crystal display device with enhanced utilization efficiency of light from light source |
摘要 |
A front light includes a light guide panel, a light guide bar placed along an end face of the light guide panel, and light-emitting elements placed at both ends of the light guide bar. A cover member including a reflecting-surface covering portion for covering an end on the reflecting-surface side of the light guide panel, a light-guide covering portion for covering the light guide bar, and an emergent-surface covering portion for covering an end on the emergent-surface side of the light guide panel is mounted so as to cover at least the light guide bar and the ends of the light guide panel. The reflecting-surface covering portion protrudes longer in the light guide direction than the emergent-surface covering portion.
