Abstract
The light emitting display apparatus may include a pixel area disposed at a substrate and configured to have an emission area and a non-emission area, a planarization layer disposed at the substrate, and a light emitting device layer disposed at the emission area and the non-emission area above the planarization layer. The light emitting device layer may include a barrier layer disposed at the boundary area between the emission area and the non-emission area. The light emitting display apparatus may be capable of preventing a leakage current between adjacent pixels.
