The present invention presents a stereoscopic image device comprising: a first polarizing beam splitter (PBS) for spatially splitting image light emitted from a projector into one or more transmitted light beams and one or more reflected light beams according to polarization components, and emitting the split image light; a first modulator performing modulation so as to have circularly polarized light beams different from each other, according to the alternate emitting, to a left image and a right image, of transmitted light in a time-division manner, such that the transmitted light beams are emitted at a screen; a second modulator performing modulation so as to have circularly polarized light beams different from each other, according to the alternately emitting, to a left image and a right image, of reflected light in a time-division manner, such that the reflected light beams are emitted at a screen; and a second PBS arranged between the second modulator and 3D glasses so as to block light having a specific polarization component, which is not converted into circularly polarized light by the second modulator. |
