摘要:
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.

The invention provides a structure to attach a liquid crystal panel to a prism, which enables further enhancements in cooling capabilities. The structure includes a storing member fixed on a base and holding a holding frame, where a liquid crystal panel is held. Erected pieces to form a space to receive the holding frame are formed protruding on both left and right sides at the light incident side. Protrusions to form an air path with a cross-dichroic prism are formed on both left and right sides on the light emitting side. The liquid crystal panel is attached to the cross-dichroic prism through a holding member having an opening at a portion corresponding to the panel face of the liquid crystal panel.

A liquid crystal panel unit is provided on the light incident face of a prism combining body. The unit has a light valve frame plate for holding a liquid crystal panel and a fixing frame plate fixed onto the light incident face with an adhesive layer. The light valve frame plate is screwed onto the fixing frame plate with a medial frame therebetween. By using wedge members, by adjusting the position of the light valve frame plate on the light incident face, it is possible to precisely position and fix the liquid crystal panel which is held there so that it is possible to control the shifted amount of the pixel alignment and precisely adjust the focus. Thus, it is possible to easily improve the accuracy. Furthermore, the fixing frame plate and the light valve frame plate are composed of materials having linear expansion coefficients ranging from 1/4 to four times that of the prism combining body and from 1/5 to five times that of the fixing frame plate, respectively.

A liquid crystal panel unit is attached to a light incident surface of a prism composite. The liquid crystal panel unit includes a panel frame plate holding a liquid crystal panel, and a fixation frame plate glued and fixed to the light incident surface. The panel frame plate is fastened to the fixation frame plate by screws through an intermediate frame plate. By using wedges, the position of the panel frame plate with respect to the light incident surface is adjusted. This allows the liquid crystal panel to be reliably positioned and fixed so that the deviation amount in pixel matching is minimized and the focus adjustment can be accomplished correctly.
