摘要： A projection type image display device of superior reliability, repairability and maintainability is provided. Support members 331 disposed between liquid crystal panels and a prism are made of a thermoplastic polymer material, and the liquid crystal panels and the prism are fixed to each other by heat-fusion 500 of the support members. When it is necessary to remove a faulty part the fused portion of the support member can be removed, thereby permitting the expensive liquid crystal panel to be taken out and re-utilized without any damage to it.

摘要： PROBLEM TO BE SOLVED: To provide a video image device having high image quality by preventing unnecessary light having an angle or spread other than normal light made incident on a light valve means without feeding it to a projection part.
SOLUTION: In a liquid crystal projector, black high polymer material whose reflectance is ≤20% is used for a holder part for supporting the light valve means. Even when the unnecessary light is cast to the holder part, it is mostly absorbed by the holder part and is not fed to a following stage, so that the deterioration of the quality of a projected video is prevented.

摘要： PURPOSE:To provide a structure with which a cabinet and a placing table can be positioned and the cabinet can be simultaneously prevented from falling down. CONSTITUTION:Concerning this structure, a positioning member 4 is fitted on a placing table 5, and a slope 4b and a guide groove 4a provided at the positioning member 4 are matched with an inclined groove 2 and a semicircular projection 3 provided at the bottom part of a cabinet 1 to be mounted. Since positioning and falling-down prevention can be simultaneously attained, after the cabinet is mounted on the placing table, the processing of falling-down prevention is not missed and it is safe. Further, since the positioning member and the falling-down proofing member are integrally formed, cost can be reduced.

摘要： PROBLEM TO BE SOLVED: To obtain accurate positioning performance and complete cooling performance by fixing a 1st fixing member for fixing a light valve and a 2nd fixing member directly fixed on a prism by using surfaces parallel with the fixed surface of the light valve and opposed to each other. SOLUTION: A light valve position adjusting fitting 603 is fixed on specified one surface of the prism 604 and a polarizing plate on an emitting side is provided in a hole provided at the center part of the surface so as to be directly stuck to the prism 604. Thus, the polarizing plate on the emitting side and the fitting 603 are fixed on the same plane. The sticking surfaces provided at four corners of the fitting 603 are positioned separately from the fixed surface onto the prism 604 by a specified distance in the light valve direction so as to form a plane perpendicular to the optical axis of the light valve. The fixed surface onto the prism 604 and the sticking surface of the fitting 603 are coupled with a coupling surface perpendicular to the optical axis of the light valve and parallel with cooling air from a downside.
