PROJECTION TYPE IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a projection type image display device capable of suppressing the variation of an image forming position due to the expansion or contraction of an image display element caused by the temperature change of the element and obtaining a fine projection image. SOLUTION: The variation of the image forming position due to expansion or contraction can be suppressed by fixing the image display element so as not to rotate it around the center part of an effective display area by an image display element fixing method. Mechanical fixing means such as a pin, a dowel and a hole are utilized as the fixing means. COPYRIGHT: (C)2003,JPO
