ABSTRACT:
A compact displaying optical system capable of reducing a speckle noise and a loss of light amount is disclosed. The displaying optical system comprises a light source which emits coherent light, and a polarization control element which has a first area and a second area where light components of the light enter, respectively. The polarization control element makes the polarization state of the light component entering the first area different from that of the light component entering the second area.
