Abstract: A light source unit includes a light source which emits a light bundle in one direction; a polarizing unit which is formed to selectively transmit a certain polarized light of a certain wavelength in the light bundle; and a reflection unit which is formed so as to delay the phase of the polarized light so that the polarized light is reflected by the polarizing unit, convert one part of the wavelength of the polarized light, and reflect the polarized light toward the polarizing unit.
