A display device includes a substrate, a plurality of first electrodes, a light-emitting lamination, a plurality of second electrodes, and one or more protruding layers. The plurality of first electrodes extend in parallel to each other on the substrate. The light-emitting lamination covers the plurality of first electrodes. The plurality of second electrodes extend across the light-emitting lamination and extend in parallel to each other at an angle with respect to an extending direction of the first electrodes. The one or more protruding layers are formed on the substrate and protrude from a side end of the light-emitting lamination in an extending direction of the second electrodes. Respective portions of the plurality of second electrodes which extend outside of the light-emitting lamination are formed on the one or more protruding layers.
