1. A light emitting display apparatus, comprising:
a substrate;
a pixel area disposed at the substrate and configured to have an emission area and a non-emission area;
a planarization layer disposed at the substrate, the planarization having a groove; and
a light emitting device layer disposed at the emission area and the non-emission area at the planarization layer,
wherein the light emitting device layer includes a barrier layer disposed at the boundary area between the emission area and the non-emission area,
wherein the light emitting device layer includes:
a first electrode;
a self-light emitting portion at the first electrode; and
a second electrode at the self-light emitting portion,
wherein the barrier layer is disposed between the first electrode and the second electrode, and
wherein the self-light emitting portion includes a first portion disposed at a remaining portion of the planarization layer except the groove and a second portion disposed in the groove, and
the barrier layer is disposed between the first portion and the second portion.
