Abstract: It is to provide a projection type display apparatus which enhances the contrast performance while minimizing a reduction in the brightness by blocking a light beam which would decrease the contrast through the use of diaphragms provided in both of an illumination optical system and a projection lens.
[Solution] A light source portion 1 and 2, a first lens array 4, a second lens array 5, and a superposition lens 7 constitute an illumination optical system. An illumination diaphragm 8 located in the vicinity 7 of the second lens array becomes a diaphragm aperture in a rectangular shape when being narrowed, wherein a side of the diaphragm aperture in the rectangular shape and longer side directions of the lens cells of the second lens array 5 are perpendicular or parallel to each other. A liquid crystal display device 17 modulates incident light. A projection lens 19 enlarges and projects modulation light. A projection lens diaphragm 20 becomes a diaphragm aperture in a rhombus shape when being narrowed, wherein a diagonal line of the diaphragm aperture in the rhombus shape and directions of sides of lens cells in a pupil image of the second lens array 5 which is formed in a pupil position of the projection lens are perpendicular or parallel to each other.
