Abstract
The present invention provides a polarized light splitting device including two right triangular prisms bonded to each other at inclined surfaces thereof via a polarized light splitting coating disposed between the inclined surfaces, in which the polarized light splitting coating includes a first polarized light splitting coating layer formed by alternately laminating a first low refractive index coating made of a first low refractive index material having a compressive stress and a high refractive index coating made of a high refractive index material and a second polarized light splitting coating layer formed by alternately laminating a second low refractive index coating made of a second low refractive index material having a tensile stress and the high refractive index coating.
