Projector

[0022]A projector according to the present embodiment is a projection-type image display apparatus that displays a color image on a screen. The projector according to the present embodiment uses a laser light source that produces high-luminance, high-power light, such as a semiconductor laser, as a light source of an illuminator.

[0023]FIG. 1 is a plan view showing a schematic configuration of the projector according to the present embodiment.

[0024]A projector 1 includes an illuminator 100, a light modulator 200, and a projection optical apparatus 300, as shown in FIG. 1. In the projector 1, an illumination optical axis of illumination light outputted from the illuminator 100 is called an optical axis AX. An XYZ orthogonal coordinate system is used in the following description as required. The direction Z corresponds to the upward / downward direction of the projector, the direction X corresponds to the direction parallel to the optical axis AX, and the direction Y corresponds to the d...

[0079]The configuration of a projector according to a second embodiment will subsequently be described. The present embodiment differs from the first embodiment in terms of the position of the correction lens in the illuminator, and the other configuration is the same in the two embodiments. The following description will be primarily made of where the correction lens is disposed and the effect provided by the thus disposed correction lens. The same members and configurations as those in the first embodiment have the same reference characters and will not be described in detail.

[0080]FIG. 9 is a top view of an illuminator in the present embodiment. In FIG. 9, an illuminator 101 is viewed from the side facing the positive side of the direction Z toward the negative side of the direction Z. The illuminator 101 in the present embodiment includes a light source unit 111, the lens integrator unit 70, the polarization converter 73, and the superimposing lens 74, as shown in FIG. 9.
