<p>The purpose of the present invention is to provide a stereoscopic imaging device capable of minimizing optical energy loss and improving image quality. To this end, the present invention provides a stereoscopic imaging device comprising: a polarizing beam splitter for splitting incident light in at least three different directions by reflecting or passing through the incident light according to polarization components; a reflection member for reflecting the light reflected from the polarizing beam splitter towards a screen direction; at least one modulator for modulating the light reflected from the reflection member and the light which has passed through the polarizing beam splitter; and a refraction member for refracting the light to be incident to the polarizing beam splitter by being arranged in the traveling direction of the light to be incident to the polarizing beam splitter.</p>
