Abstract:
A projection display device that modulates a plurality of color light beams through a plurality of modulation elements in response to image information, synthesizes the modulated color light beams by a light synthesizing element, and enlarges and projects the synthesized color light beams by a projection system, the projection display device comprising:a frame system fixed to a light incident face of the light synthesizing element;a modulation element frame detachably mounted to the fixed frame system that holds the modulation elements;a position adjusting member that positions the modulation element frame and the fixed frame system; anda fixing member that fixes the modulation element frame to the fixed frame system with the position adjusting member therebetween,the fixed frame system having a fixing section that fixes the position adjusting member, and having a deformable section in a portion other than the fixing section, that elastically deforms compared to the fixing section.
