Display device capable of improving light extraction efficiency

A display device comprising:

• a thin-film transistor disposed on a substrate;
• a first overcoat layer disposed on the thin-film transistor and comprising a groove portion;
• a reflective layer disposed on the groove portion of the first overcoat layer;
• a color filter disposed on the reflective layer and located in the groove portion;
• a second overcoat layer disposed on the color filter and the reflective layer;
• a first electrode disposed on the second overcoat layer and connected to the thin-film transistor;
• a bank layer disposed on the first electrode and comprising an open portion exposing the first electrode;
• an organic layer disposed on the bank layer and the first electrode;
• and
• a second electrode disposed on the organic film layer,
• wherein the reflective layer is disposed to be extended outside of edges of the color filter in a horizontal direction according to an upper surface of the first overcoat layer,
• wherein a size of a planar surface of the reflective layer is larger than a size of a planar surface of the color filter, and
• wherein at least a portion of the reflective layer is disposed between the first overcoat layer and the color filter.
