Abstract: The purpose of the present invention is to obtain an insulation film with high reliability, the insulation film and a wiring line being not susceptible to the occurrence of a crack due to thermal stress difference between the insulation film for wiring insulation or a protective film and inorganic materials, namely a metal wiring line, an inorganic light emitting diode chip and a substrate. In order to achieve the purpose, the present invention provides a display device which comprises at least a metal wiring line, a cured film, an inorganic insulation film and a plurality of light emitting elements, wherein: the cured film is obtained by curing a resin composition that contains a resin (A); each of the light emitting elements is an inorganic light emitting diode that is provided with a pair of electrode terminals on either surface; the pair of electrode terminals are connected to a plurality of the metal wiring lines that extend in the inorganic insulation film and the cured film; the display device is configured such that electrical insulation is maintained among the plurality of metal wiring lines by means of the cured film and the inorganic insulation film; the display device comprises a plurality of the cured films; and the inorganic insulation film is arranged so as to be in contact with at least a part of the interlayer between the plurality of cured films.
