1. A projection type image display apparatus comprising:

  • an electroluminescence element with three luminescent layers emitting three primary colors layered, each of the luminescent layers having emission pixels arranged in two-dimensional matrix form and emitting an image modulation pattern light including an intensity distribution of respective colors according to an input signal based on image information; and

    a projection optical system that projects light emitted from the electroluminescence element onto an object and displays an additive color mixture image, wherein said projection optical system has axial chromatic aberration in such a way that the positions of the plane of the luminescent layer and the plane of the object have an optically conjugate relationship at an emission intensity median point wavelength of a waveband of each of the colors.
