摘要： An output light from an light source lamp unit 8 in a projection-type display apparatus illuminates liquid-crystal light valves 925R, 925G and 925B for three colors via an integrator optical system 923. A superimposing lens 930 that is a component of the integrator optical system 923 as a uniform illumination optical system is arranged such that the mounting position of the superimposing lens 930 is fine-adjustable in a direction orthogonal to an optical axis 1a. By fine-adjusting the mounting position of the superimposing lens 930, the position of an illumination area B is adjusted such that the illumination area includes the image forming area A of the liquid-crystal light valve. It is not necessary to assure a wide margin around the image forming area A to cover the offset of the position of the illumination area B. As a result, the utilization of illumination light is heightened and a bright projected image results.

摘要： A polarizing conversion device in accordance with the invention includes a first optical element for condensing an incident beam and forming a plurality of intermediate beams spatially separated from one another, and a second optical element for spatially separating each intermediate beam into two polarized beams and aligning the polarization directions of the polarized beams, thereby obtaining the same type of polarized beams. In the second optical element, a shading plate is placed to prevent light from directly entering a section corresponding to a reflecting plane of a polarizing separation unit array. Since the ability of separating the intermediate beam into two polarized beams is thereby enhanced, it is possible to perform conversion into the same type of polarized beams polarized in the same direction, with high efficiency.

摘要： A projection-type display apparatus in accordance with the invention reduces the margin formed around the image forming range of the light valves, and forms a bright projected image. Emitted light from a light source lamp unit of a projection-type display apparatus illuminates liquid crystal light valves of each color via an integrator optical system. First and second lens plates of an integrator optical system that serves as a uniform illuminating optical system are disposed such that the attachment position thereof is capable of fine adjustment in a direction vertical to the optical axis. By performing fine adjustment of the attachment position of these, the forming position of the illumination range B can be adjusted to include the image forming range A of the liquid crystal light valves. Accordingly, there is no need to provide a wide margin around the image forming range A, taking shifting of the forming position of the illumination range B into consideration. Thus, efficient usage of the illumination light can be increased, thereby improving the brightness of the projected image.

摘要： A screen in which observation distance may be adjusted while maintaining image brightness and a projection system using the screen. In a light control layer of a screen, a first angle region that determines a diffusion distribution of a reflected light is different according to the screen position in a control direction in which light diffusion control is performed. Accordingly, a diffusion distribution of image light emitted from a screen surface is adjusted to be tilted downward by an upper end and upward by a lower end according to the screen position. Thus, for example, a size of a diffused angle range is maintained to be 30°, and a direction in which the image light is diffusion-emitted corresponds to an assumed position of an observer. The projection image can be observed while maintaining brightness of an image and the observation distance can be adjusted to be short.
