摘要： A projection lens unit and a projection mirror unit are moved relative to an illumination optical system, between a first position where an image is projected in a shape that is longer along a direction of projection onto a projection plane and a second position where an image is projected in a shape that is longer along a direction perpendicular to the direction of projection onto the projection plane. When the projection lens unit and the projection mirror unit are located in the first position, a vertically long image is projected onto the projection plane (portrait display). In this state, when the projection lens unit and the projection mirror unit are moved to the second position, a horizontally long image is projected onto the projection plane (landscape display).

Each light source is a light source in which a plurality of LEDs (light-emitting diodes) are arranged in the same plane surface. The first light source, the second light source, and the third light source are arranged on the same plane surface. Furthermore, lines connecting the first light source, the second light source, and the third light source form a triangle. Light fluxes (primary optical axes) of each light source are parallel with each other.

摘要： An illumination apparatus includes a plate-like separation optical element having a dichroic surface and a PBS surface. The dichroic surface reflects green component light and transmits yellow component light. The PBS surface transmits P polarization component light and reflects S polarization component light. The separation optical element combines red component light entering from a certain direction and transmitted through the dichroic surface, with yellow component light entering from a different direction and reflected by the PBS surface, and leads a combined light towards a red liquid crystal panel. The separation optical element combines green component light entering from the certain direction and reflected by the dichroic surface, with yellow component light entering from the different direction and transmitted through the PBS surface, and leads a combined light towards a green liquid crystal panel.

摘要： Modulated light (image light) which has been modulated by passing through a liquid crystal display panel passes through an apical angle variable prism (so-called, a vari-angle prism) and then is enlarged and projected by a projection lens. The apical angle variable prism is configured to change the prism apical angle with, for example, an electromagnetic actuator. The microcomputer calculates a projection optical axis correction value based on hand shake detection signals from a sensor and controls the aforementioned actuator based on the correction value. With this control, shakes of projected images due to hand shakes are prevented.

摘要： The auxiliary light source has LED chips respectively emitting red lights arranged therein in an array shape, and has lens cells for parallelizing light arranged therein on the light exit side of the LED chips, for example. The LED chip is arranged in correspondence with each of lenses composing a pair of fly's eye lenses, and the pair of lenses introduces the light emitted from the LED chip into the whole surfaces of liquid crystal panels. A mixing mirror transmits white light emitted from a main light source and reflects light emitted from the auxiliary light source, and mixes the white light and the auxiliary light respectively emitted from both the light sources and introduces the mixed lights into the pair of fly's eye lenses.
