1. A display device, comprising:
a first substrate including a plurality of sub-pixels;
a thin film transistor in each sub-pixel of the first substrate;
an organic light emitting element in each sub-pixel of the first substrate;
an insulating layer over the thin film transistor and the organic light emitting element;
a first touch electrode and a second touch electrode over the insulating layer and spaced apart from each other;
a passivation layer covering an upper surface of each of the first touch electrode and the second touch electrode; and
a second substrate disposed over the passivation layer,
wherein a plurality of first concave portions are formed in the insulating layer, and a concave portion among the plurality of first concave portions is filled with the passivation layer to form an adhesive reinforcing portion.
