ABSTRACT:
A projection type image display device superior in reliability and also superior in both repairability and maintainability is to be provided at a low cost. Support members disposed between liquid crystal panels and a prism are made of a thermoplastic polymer material, and the liquid crystal panels and the support members are fixed to each other by heat-fusion of the support members. When it is necessary to remove a liquid crystal panel which is at fault for example from the corresponding support member, the fused portion on the support member side which less expensive is cut off, thereby permitting the liquid crystal panel which is expensive to be taken out re-utilizably without any damage thereto.
