Abstract
A lighting device includes a plurality of light-transmitting guide plateslaminated in at least three layers and a plurality of light emitting elementsarranged so as to oppose to respective lateral sides of the light-transmitting guide platesto allow luminance flux in different color with respect to each light-transmitting guide plate to be incident on the corresponding light-transmitting guide plate. Each of the light-transmitting guide plateshas a plurality of reflecting surfacesformed on the backside of the plate to change a propagation direction of the luminance flux propagated in the each light-transmitting guide plate, allowing the luminance flux, of which propagation direction has been changed by the reflecting surfaces, to be emitted from the front side of the each light-transmitting guide plates.
