ILLUMINATING APPARATUS, IMAGE DISPLAY APPARATUS, AND PROJECTOR

摘要

An illuminating apparatus (100, 500) includes at least two solid light-emitting elements (101a, 101b) including a first solid light-emitting element (101 a) and a second solid light-emitting element (101b); a polarized-light combining unit (104) that combines a first polarized light of a first oscillation direction and a second polarized light of a second oscillation direction substantially perpendicular to the second oscillating direction to guide the first polarized light and the second polarized light to an illumination direction by transmitting or reflecting the first polarized light and reflecting or transmitting the second polarized light; and a phase modulating element (106) that converts a polarized light from the polarized-light combining unit (104) into either of the first polarized light and the second polarized light.
