Abstract
An electroluminescent display device according to an exemplary embodiment of the present disclosure includes an anode over a substrate, an organic layer on the anode, a cathode on the organic layer, an encapsulation layer over the cathode, a foreign material present between the anode and the organic layer, the cathode, and the encapsulation layer and a barrier layer over the encapsulation layer to cover the foreign material, so that penetration of moisture and oxygen is prevented and thus, dark spot defects and pixel defects caused by foreign substances can be repaired.
Claims37
An electroluminescent display device, comprising:
- an anode over a substrate;
- an organic layer on the anode;
- a cathode on the organic layer;
- an encapsulation layer over the cathode;
- a foreign material present between the anode and any one of the organic layer, the cathode, and the encapsulation layer;
- and
- a barrier layer over the encapsulation layer to cover the foreign material.
An electroluminescent display device, comprising:
- an anode over a substrate;
- an organic layer on the anode;
- a cathode on the organic layer;
- an encapsulation layer on the cathode;
- and
- a primary barrier layer on the encapsulation layer,
- wherein the primary barrier layer is on a foreign material present between the substrate and the encapsulation layer,
- wherein the foreign material has a first dimension in a first direction,
- wherein the primary barrier layer has a second dimension in the first direction, and
- wherein the second dimension of the primary barrier layer is greater than the first dimension of the foreign material to sufficiently cover the foreign material.
