Beschreibung
Zusammenfassung:	A light guide plate includes a light introduction surface to receive light supplied from a light source module and a light emission surface to emit the light outward, the light emission surface having a larger area than the light introduction surface. The light guide plate is of a material that transmits light and absorbs light in an absorption wavelength band. The light guide plate further includes a plurality of color patterns to convert the light supplied from the light source module into light in the absorption wavelength band.
