A manufacturing method of an optical device includes an optical component housing operation S1 for housing a plurality of optical components in a casing body, an optical component positioning operation S2 for adjusting the positions of the optical components by shifting the optical components to position by positioning members at predetermined positions on an illumination optical axis of a light beam irradiated by a light source, and an optical component position fixing operation S3 for fixing the positions of the optical components on the casing body after the optical component positioning operation S2. The optical component housing operation further includes a positioning member inserting process for inserting the positioning members to holes on the casing body, an optical component housing process for housing the optical components in the casing body, and a positioning member abutting process by which the positioning members abut on the optical components.

An optical device is disposed with: a swollen portion that is attached to the underside of a reflective surface of a reflective mirror, swells in an outward direction of the reflective mirror and is configured as part of a spherical surface. A mirror orientation adjustment lever that is attached to the underside of the reflective surface of the reflective mirror, extends along the underside of the reflective mirror, and protrudes from an end edge of the reflective mirror when seen planarly. The reflective mirror is disposed along a side wall of an optical parts-use casing. The side wall includes, at the position where the reflective mirror is disposed, a spherical concave portion corresponding to a spherical surface of the swollen portion, and when the reflective mirror is disposed at the disposition position, the swollen portion is supported by the spherical concave portion.

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.
