ELECTROLUMINESCENT DISPLAY DEVICE

An electroluminescent display device includes a substrate (101) including an active area (AA) and a non-active area (NA) surrounding the active area (AA); a planarization layer (105) over the substrate (101); an anode (151) on the planarization layer (105); an organic layer (152) on the anode (151) and absent at a laser ablation area (LA) in the non-active area (NA) to surround the active area (AA), a portion of the organic layer (152) disposed outside the laser ablation area (LA); a cathode (153) on the organic layer (152) and absent at the laser ablation area (LA), a portion of the cathode (153) disposed outside the laser ablation area (LA); an encapsulation substrate (109, 309) above the substrate (101); and a dam (140, 240, 340) at the laser ablation area (LA) between the substrate (101) and the encapsulation substrate (109, 309).
