Fixing plate, optical device and projector
First Claim
1. A fixing plate attached at a luminous-flux exit side of a light modulator device that modulates a luminous flux emitted from a light source in accordance with image information and forming an optical image, and that fixes the light modulator device on a color-synthesizing optical device that synthesizes colors of light exited from the light modulator device, the fixing plate comprising:
- a plate part in a rectangular plate form fixing the light modulator device and formed with an opening that transmits a luminous flux exited from the light modulator device,a cutout in a groove form being formed extending nearly orthogonal to a lengthwise of each side, in four sides of a luminous-flux incident surface or luminous-flux exit surface of the plate part.

Abstract
The invention provides a fixing plate, optical device and projector capable of preventing against color unevenness occurrence and pixel deviation. Specifically, in each of the four sides of a luminous-flux exit surface of a plate part of a fixing plate, there can alternately be formed a first cutout in a groove form extending from an opening toward an outer edge of the plate part and nearly orthogonal to a lengthwise of each side, and a second cutout in a groove form extending from the outer edge toward the opening and nearly orthogonal to the lengthwise of each side.

5. A fixing plate attached at a luminous-flux exit side of a light modulator device that modulates a luminous flux emitted from a light source in accordance with image information and forming an optical image, and that fixes the light modulator device on a color-synthesizing optical device that synthesizes colors of light exited from the light modulator device, the fixing plate comprising:
-
a plate part in a rectangular plate form fixing the light modulator device and formed with an opening that transmits a luminous flux exited from the light modulator device, a cutout in a groove form being formed extending nearly orthogonal to a lengthwise of each side, in four sides of a luminous-flux incident surface or luminous-flux exit surface of the plate part, a number of the cutouts being the value resulting when an expansion coefficient of the fixing plate is divided by an expansion coefficient of the color-synthesizing optical device and then is changed into an integer, or the above value changed into an integer is multiplied by an integer. - View Dependent Claims (6, 7)
