Abstract: LED display devices emit light in all directions. Therefore, light is absorbed by peripheral insulating films for insulation of wiring, protective films, partition walls, and the like, and the light-extraction efficiency of a display becomes reduced, resulting in insufficient luminance. According to the present invention, such a problem is solved. This display device comprises at least: a metal wiring; a cured film; and a plurality of light-emitting elements. Each of the light-emitting elements is equipped with a pair of electrode terminals on one surface thereof. The pair of electrode terminals are connected to a plurality of strands of the metal wiring extending in the cured film. The plurality of strands of the metal wiring are configured to maintain electrical insulating properties due to the cured film. The cured film is obtained by curing a resin composition containing a resin (A). The transmittance of the cured film with respect to light having a wavelength of 450 nm is 80-100% at a thickness standard of 5 μm of the cured film.
