摘要：
A light-guide sheet includes a light transmissive film substrate, and luminescent protrusions formed at predetermined points on the substrate. At least one of the substrate and each of the luminescent protrusions is colored to a color tone that absorbs yellow light more than blue light. Alternatively, a reflective layer colored to a color tone that absorbs yellow light more than blue light is provided on at least one of the top and bottom faces of the substrate.
