<P>PROBLEM TO BE SOLVED: To provide a combiner optical system which can prevent the degradation of appearance caused by a polarizing beam splitter looking dark, and to provide a loading type display apparatus using the same. <P>SOLUTION: The combiner optical system 11 includes the polarizing beam splitter 16 which transmits p-polarized light components and reflects s-polarized light components, a reflection member 17 which reflects the p-polarized light components passed through the polarizing beam splitter toward the polarizing beam splitter and a quarter wavelength plate 18 which is arranged between the reflection member and the polarizing beam splitter 16. Reflectivity of the s-polarized light components by the polarizing beam splitter 16 is ≥0.2 and ≤0.8. <P>COPYRIGHT: (C)2009,JPO&INPIT |
