摘要： A projection display apparatus includes a light source (1), an illumination system (8), a reflection system (9), a reflection-type light modulator (10), a lens element (11), and a projection system (12). The optical axis (8a) of the illumination system (8) and the optical axis (12a) of the projection system (12) are skew lines. The lens element (11) allows the exit pupil (8b) of the illumination system (8) to be conjugated substantially with the entrance pupil (12b) of the projection system (12). Thus, the reflection-type light modulator (10) and the projection system (12) can be arranged coaxially. Moreover, mechanical contact or interference between the optical components can be eliminated, and the space can be utilized efficiently. This configuration can provide an inexpensive compact projection display apparatus using a reflection-type light modulator.

摘要： A conventional optical illumination device has a problem in which uneven brightness appears in an inclining direction when an illuminated region inclined with respect to an optical axis is illuminated. An optical illumination device is formed by using a front optical illumination system, an eccentric lens, and a relay lens. The front optical illumination system is composed of a lamp, an elliptical-surface mirror, a UV-IR cut filter, a condenser, a first lens, and a second lens. The relay lens conjugates a second light-emitting surface and a third light-emitting surface that are inclined with respect to an optical axis. The eccentric lens is made eccentric with respect to an optical axis, effectively emits light, which is emitted from the second lens, to the relay lens, and inclines the second light-emitting surface in a direction in which brightness gradient appearing on the relay lens is canceled.
