摘要： A method for manufacturing an optical element in which a display quality of a projection image is improved is provided. The method is for manufacturing an optical element having a polarization plate of which one side a transmissive member is bonded. The method includes preparing a light source, a polarization plate, a transmissive member, a certificating polarization plate and a spectrophotometer; arranging the polarization plate, the transmissive member, and the certificating polarization plate between the light source and the spectrophotometer; measuring a light transmittance spectrum of a predetermined wavelength at each rotational position of the transmissive member; determining the rotational position of the transmissive member that yields a smallest value for a difference between a maximum value and a minim value of the light transmittance spectrum; and bonding the transmissive member to the polarization plate at the determined rotational position.

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： An illumination device of the invention is an illumination device 100A including an ellipsoidal reflector 130, an arc tube 120, a sub-mirror 122, and a parallelizing lens 140A, which is characterized in that on a light incident-surface 140Ai of the parallelizing lens 140A is formed a reflection reducing layer 142A optimized to match with a light, which is, of the lights emitted from a luminescent center P of the arc tube 120, a light that is emitted toward the ellipsoidal reflector at any angle of 60° to 80° with respect to an illumination optical axis 100Ax and goes incident on the light incident-surface 140Ai of the parallelizing lens 140A after the light is reflected on the ellipsoidal reflector 130. The illumination device of the invention is thus able to further improve efficiency of light utilization as well as further reduce unwanted stray lights by further reducing overall reflectance of the light incident-surface or the light exiting-surface of the parallelizing lens. A projector of the invention, by including the illumination device capable of further improving efficiency of light utilization as well as further reducing unwanted stray lights, serves as a high-intensity, high-quality projector.

摘要： A red-reflecting film and a blue-reflecting film are formed in a substantially X shape on joint surfaces defined by the respective side faces of four columnar prisms or right-angle prisms. The red-reflecting film is continuously formed without separating at an intersection of the two reflecting films. The blue-reflecting film is, on the other hand, divided into two pieces by the red-reflecting film and an adhesive. It is preferable that that four columnar prisms are obtained from one block of sheet glass. This arrangement ensures an improvement in properties of a resulting light-selective prism.

摘要： To provide a projection display device which can easily produce a high contrast, bright projection image, without obliquely mounting the light source. In a projection display device, a condenser lens is disposed such that its optical axis is disposed at a location parallel to an optical axis of a light source by moving the optical axis of the condenser lens with respect to the optical axis L of the light source in substantially the same direction that an optical axis of a projection lens 60 is moved with respect to the optical axis of the light source. Therefore, light can obliquely illuminate a liquid crystal light valve, and can be efficiently guided to the projection lens. Consequently, a high contrast, bright projection image can be easily provided.

摘要： A .lambda./4 phase plate 821 is placed in an optical path between a blue light liquid crystal valve 811 and a cross-dichroic prism 813. S-polarized blue light incident on the blue Light liquid crystal light valve 811 is transmitted by an s-polarized light transmitting polarizer 811a without change, modulated by a liquid crystal panel 811b and a part thereof is converted into p-polarized light, and the p-polarized light is transmitted by a p-polarized light transmitting polarizer 811c to be emitted. The emitted p-polarized light is incident on the .lambda./4 phase plate and converted into circularly polarized light to be emitted, and is incident on the cross-dichroic prism 813. The circularly polarized light reflected from a red reflecting film 831 and a blue reflecting film 833 and incident on the .lambda./4 phase plate 821 again is converted into s-polarized light to be illuminated on the blue light liquid crystal valve 811, but is cut off by the p-polarized light transmitting polarizer 811c to prevent the influence on the liquid crystal panel 811b.
