PROBLEM TO BE SOLVED: To obtain a projection type display device which is compact and excellent in heat radiation performance.SOLUTION: A projection type display device 100 comprises a light source 121, a housing 103, a light source heat radiation member 104, and a cover plate 107. The light source 121 emits light to be projection light. The housing 103 holds the light source 121. The light source heat radiation member 104 absorbs the heat generated by the light source 121 and radiates it. The cover plate 107 covers an opening 103b provided in the housing 103 and is attached to the housing 103 in contact with and along with the outer surface thereof. The light source 121 thermally contacts with the cover plate 107 through the opening 103b, and the light source heat radiation member 104 is arranged on the rear surface side of a thermal contact position of the light source 121 on the cover plate 107. |
