In an electron beam display in which electron-emitting devices 10 each emit an electron beam 5 that is non-uniform on the electron beam 5 irradiation surface of a corresponding pixel 7, the present invention allows possible luminance unevenness to be prevented while maintaining the brightness of a screen. The electron beam display includes light transmission suppressing portions 12 configured to cover respective light-transmitting apertures 8 each formed in the corresponding pixel 7 in order to allow light to be derived through the aperture, corresponding to a position on the electron beam 5 irradiation surface where the pixel 7 irradiated with the electron beam 5 by the electron-emitting device 10 exhibits the highest current density; and to have 10% to 28% of the aperture 8 in area.
