Abstract
A polarized light source comprises at least one non-polarized light source for emitting light, a reflective type polarizer for allowing a specific polarized light to pass, a reflective surface for reflecting light, and a phase converting device for changing a polarization state of a polarized light. By properly disposing the reflective surface and the phase converting device along the light propagating path, the non-polarized light can be transformed into the specific polarized light efficiently and finally be emitted from the polarized light source.
