发明名称 PROJECTOR
摘要 A projector includes: a light source that emits light having an asymmetric illuminance distribution; a light modulation device that modulates the light emitted from the light source; and an optical member disposed in an optical path between the light source and the light modulation device, the optical member changing the illuminance distribution of the light from the light source, wherein the optical member changes the illuminance distribution of the light passing therethrough in such a way that a highest illuminance area in the illuminance distribution of the light after passing through the optical member is shifted toward the center of the optical member as compared with the position of the highest illuminance area in the illuminance distribution of the light before incident on the optical member.
