Abstract
A display device includes an array substrate, a plurality of mounting electrodes provided to the array substrate, a columnar conductor for coupling provided to each of the mounting electrodes, a plurality of light-emitting elements provided to the array substrate, a first electrode and a second electrode provided to a surface of each of the light-emitting elements facing the array substrate, the first electrode being coupled to one of an anode and a cathode of the light-emitting element, the second electrode being coupled to the other of the anode and the cathode of the light-emitting element, and a coupling member covering each of the first electrode and the second electrode. The columnar conductor is made of material harder than the coupling member, and an end of the columnar conductor on the light-emitting element side is electrically coupled to the coupling member.
