Classification: CPC G  H | IPC H

Claim 18:
19. 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 touch sensor over the insulating layer;
a passivation layer covering the touch sensor; and
a second substrate disposed over the passivation layer,
wherein a plurality of concave portions are formed in the insulating layer, and a concave portion among the plurality of concave portions is filled with the passivation layer to form an adhesive reinforcing portion,
wherein the insulating layer includes:
an inorganic encapsulation layer;
an organic encapsulation layer over the inorganic encapsulation layer;
a buffer layer over the organic encapsulation layer; and
an interlayer over the buffer layer, and

wherein the concave portion is formed in the interlayer and the buffer layer to expose a surface of the organic encapsulation layer, and the adhesive reinforcing portion is formed inside of the concave portion so that the adhesive reinforcing portion contacts the exposed surface of the organic encapsulation layer.
