Abstract
The present invention provides an optical device that achieves reduction in size, reduction in manufacturing costs, improved image quality, and so forth, by simplification and the like of a panel in prisms (POP) structure wherein light-modulating devices and a color synthesizing optical element are integrally formed. A POP structure is configured wherein pins integrally formed with a holding member are inserted through holes formed in the four corners of holding frames storing the liquid crystal panelsso as to fix the holding frames and holding members by adhesion. End faces of holding members opposite to the pins are fixed by adhesion to the side faces of bases fixed on the upper and lower faces of a cross-dichroic prism.
