A self−emission image display (A) comprises an output section (10) for displaying an image, a reflection section (20) so disposed behind the output section (10) that its reflecting surface faces to the output section (10), and an emission section (30) disposed behind the output section (10). The output section (10) has a linear polarization element (15) so disposed as to cover the display surface and adapted for transmitting only a predetermined linearly polarized component of the extraneous light and a phase difference film (14) disposed nearer to the emission section than the linear polarization element (15) and adapted for changing the linearly polarized light transmitted through the linear polarization element (15) and coming from the front of the display surface to circularly polarized light. The phase difference film (14) has a structure of a refraction index ellipsoid satisfying the inequalities nx>nz>ny where nx is the index of refraction along the slow axis, ny is the index of refraction along the fast axis, and nz is the index of the index of refraction in the direction of the film thickness.
