    • An illuminator includes a polarization converter that converts source light into first polarized light, a polarization separation member that separates the first polarized light of from the polarization converter and second polarized light different from the first polarized light, by reflection and transmission, a polarization switch member that reflects the first polarized light passed through the polarization separation member and changes same into the second polarized light, and a light guide having a first rod arranged between the polarization converter and the polarization separation member, a second rod arranged between the polarization separation member and the polarization switch member, and a third rod arranged on an optical path of the second polarized light separated by the polarization separation member.
    • 照明装置包括将源光转换为第一偏振光的偏振转换器,通过反射和透射分离偏振转换器的第一偏振光和与第一偏振光不同的第二偏振光的偏振分离部件,偏振切换部件 其反射通过所述偏振分离部件的第一偏振光并将其变化为第二偏振光,以及具有设置在所述偏振转换器和所述偏振分离部件之间的第一杆的导光体,配置在所述偏振光分离部件和所述偏振光分离部件之间的第二杆 所述偏振光开关部件以及配置在由所述偏振光分离部件分离的所述第二偏振光的光路上的第三杆。
