PROBLEM TO BE SOLVED: To provide a projection type display device including a light source unit for projection which can be attached to/detached from a main body, and capable of detecting a case where the light source unit for projection other than normal standardized ones is used and a case where the light source unit for projection is exchanged, and to provide the light source unit for projection. SOLUTION: In the projection type display device 1 including the attachable/detachable light source unit for projection 58, the light source unit for projection 58 includes a non-volatile storage part 55 readable from a main body, and the main body includes a light source information discrimination part 64 reading out light source information stored in the non-volatile storage part 55 of the light source unit for projection 58, and discriminating at least either of whether or not the light source unit for projection is the predetermined standardized one and whether or not the light source unit for projection is exchanged based on the light source information.
