Abstract
A light source for flat-panel display comprising reflectors each having a triangular shape in section which are stacked on top of another so as to have at least three slant faces such that at least an uppermost face of the stacked reflectors is perpendicular to a lateral side thereof, a slant face of each of the reflectors being subjected to a surface treatment such that a ray of light incident laterally to the reflectors is reflected substantially parallel to a lateral side thereof, whereby rays of colors which are incident laterally to each of the reflectors advance via the uppermost face of the stacked reflectors substantially perpendicularly.
