PROBLEM TO BE SOLVED: To obtain a projection type display device capable of achieving the lowering of the temperature of an external cabinet while it is miniaturized and thinned. SOLUTION: The projection type display device is constituted so that a sheet metal component 61 having high heat conductivity and a heat insulating sheet 62 having low heat conductivity may be arranged in space between a lamp 28 being a light source and the external cabinet. In such constitution, the temperature of the external cabinet is lowered by a thermal diffusion effect by the sheet metal component 61 having the high heat conductivity and a heat insulating effect by the heat insulating sheet 62 having the low heat conductivity while achieving the miniaturized and thinned structure where the space between the lamp 28 and the external cabinet is minimized.
