摘要： A projector includes a light source, an illumination optical system, and a color separating optical system. The color separating optical includes a dichroic mirror which reflects a first color light component of an illumination light through a first optical path by a reflection angle and transmits a second light component through a second optical path; a first mirror which bends the first optical path by a first bent angle; and a second mirror which bends the second optical path by a second bent angle. The reflection angle, the first bent angle, and the second bent angle are arranged to provide a predetermined difference between the length of the first optical path and the length of the second optical path, and the predetermined difference corresponding to a difference between focal distances of a superimposing optical element corresponding to the first and second light components.

摘要： Aspects of the invention can provide a projector capable of forming a projected image with an apparently seamless and smooth image quality in the stable state. As for the image light passed through a first unit, the polarization direction thereof can be appropriately rotated by a λ/2 phase plate, and a part of the image light can be split in the Y direction by a birefringent plate. When this is projected as it is, an image composed of a plurality of two dimensionally arranged pixels, pixels corresponding to the split image, and a black matrix area can be formed on a screen. As for the image light passed through a second unit, the polarization direction thereof can be appropriately rotated by a λ/2 phase plate, and a part of the image light can be split in the Y direction by a birefringent plate. Then, an image composed of the pixels in the previous stages, the pixels corresponding to the split images, and the black matrix area can be formed on the screen.

摘要： An object of the invention is to form a projecting image of smooth image quality inconspicuous in a joint in a stable state. With respect to image light passing through a second birefringent plate 28j set to a first state, an image light portion branched by a first birefringent plate 28i is further branched in the Y-direction. An image IM3 constructed by an original pixel PX0, a pixel PX2 corresponding to its branching image, and a black matrix area BA is formed on a screen. With respect to the image light passing through a second birefringent plate 28j set to a second state, the image light once branched by the first birefringent plate 28i is returned in the −Y direction. As this result, an image constructed by the black matrix area BA and an image provided by overlapping the branching image of the original pixel PX0 with the original pixel PX0 is formed on the screen. Namely, the same image IM3′ as an original image IM1 is formed on the screen.

摘要： A projector is provided to ensure the enhancement of contrasts while reducing the needs for alignment accuracy. The projector includes a light source, a first lens array, a second lens array, a superimposing lens, and a projection lens. The first lens array splits light emitted by the light source into a plurality of partial light beams with a plurality of small lenses that are arranged in a matrix. The second lens array includes a plurality of small lenses corresponding to the plurality of small lenses of the first lens array. The superimposing lens superimposes a plurality of partial light beams emitted by the first lens array and the second lens array on a liquid crystal panel. The projection lens projects light modulated by the liquid crystal panel. In the projector, a diaphragm having an opening that is shaped to be nearly similar to the outline of the second lens array is provided in the vicinity of an area conjugated with the second lens array.
