Projection display apparatus 1 includes light source lamp unit 8, optical lens unit 9, projection lens unit 6, and power supply unit 7. Projection lens unit 6 is disposed in the front part of outside case 2, light source lamp unit 8 is disposed in the back part of the outside case of the apparatus, and between these units 6 and 8 optical lens unit 9 and power supply unit 7 are disposed in a vertically stacked arrangement with optical lens unit 9 on the top and power supply unit 7 on the bottom. Because these large units 9 and 7 are vertically stacked, the front-back and right-left dimensions (i.e. length and width) of the overall apparatus can be reduced. An apparatus 1 that is easily portable and does not require a large installation space can therefore be achieved. Because the heavy power supply unit 7 is on the bottom, apparatus 1 is also stable when placed on a table, etc.

A method for installing an electro-optical device to a prism and a manufacturing method for a projector that permit improved positional accuracy, improved fixing operation efficiency, and a simplified fixing operation process of an electro-optical device are provided. The methods are provided with spacer mounting process steps for mounting a spacer via an adhesive agent between a panel frame assembly, which holds an electro-optical device, and a prism, position adjusting process steps for adjusting a position where the panel frame assembly is installed to the prism after the spacer mounting process steps, and panel frame assembly fixing process steps for fixing the panel frame assembly by hardening the adhesive agent after the position adjusting process steps.

A liquid crystal panel unit is attached to a light incident surface of a prism composite. The liquid crystal panel unit includes a panel frame plate holding a liquid crystal panel, and a fixation frame plate glued and fixed to the light incident surface. The panel frame plate is fastened to the fixation frame plate by screws through an intermediate frame plate. By using wedges, the position of the panel frame plate with respect to the light incident surface is adjusted. This allows the liquid crystal panel to be reliably positioned and fixed so that the deviation amount in pixel matching is minimized and the focus adjustment can be accomplished correctly.

A liquid crystal projector has three liquid crystal panels for modulating first color light, second color light, and third color light respectively. A light synthetic device synthesizes each color light modulated by the liquid crystal panels. A projection lens projects the light synthesized by the light synthetic device. Setting members set the liquid crystal panels to the light synthetic device and wedge-type spacer members adjust the position of the liquid crystal panels in their planar direction and the direction perpendicular to the planar direction.The liquid crystal panels are secured to the light synthetic device through the setting members and spacer members.

A projection display apparatus comprising a floppy disk drive device and floppy disk insertion opening in an appropriate arrangement is provided. A power supply unit, over which is disposed a floppy disk drive unit, is provided at the back of the projection display apparatus. The floppy disk drive unit is positioned offset to the left side of the projection display apparatus. A floppy disk (FD) insertion opening is positioned in a side wall at the left side of the exterior case of the projection display apparatus. An FD drive circuit board is positioned horizontally to the right of the floppy disk drive unit and slightly overlapping a drive control circuit board such that the electrical connections between the drive control circuit board and the FD drive circuit board can be made in this overlapping area. The side wall in which the floppy disk insertion opening is provided includes the operating panel in which the input/output terminals and operating switches are also disposed. This arrangement enables the floppy disk drive unit to be provided inside the projection display apparatus without using specific separate mounting members or reinforcing members therefor, and enables electrical connections between the power supply unit and control circuit board to be established via the FD drive circuit board without using separate wiring or harnesses. Operability is also improved because the floppy disk insertion opening is provided at the operating panel side.

Molten glass (G) is set and press-molded in a molding die (60) having dies (621A1, 621A2) corresponding to a lens array. After the molding, the molded article is removed from the molding die (60) and separated by bending at a bend-separation face (121C), which is a boundary part of adjacent lens arrays, so that two lens arrays are produced.
