    摘要： A light emitting display apparatus can include a substrate including a display area and a non-display area surrounding the display area, a circuit layer on the substrate, a planarization layer on the circuit layer, and a dam disposed on the planarization layer and located at a boundary between the display area and the non-display area. Also, the light emitting display apparatus can further include a division portion disposed on the dam, the division portion extending along the dam; a display area emission layer disposed in the display area; a non-display area emission layer disposed outside the dam, the dam being located between the display area emission layer and the non-display area emission layer; and a division portion emission layer disposed on an upper surface of the division portion. The division portion emission layer can be separated from the display area emission layer and the non-display area emission layer.
