Abstract
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.
