Abstract

A light emitting display device includes: a flexible substrate including a display area and a peripheral area having a bending area. The display area includes: a plurality of inorganic layers; first and second organic layers that are disposed on the plurality of inorganic layers; a black pixel defining layer that is disposed on the second organic layer; and a spacer that is disposed on the black pixel defining layer. In the bending area, the plurality of inorganic layers include a first opening formed at a position corresponding to the bending area. The first opening is filled with the first organic layer, the second organic layer is disposed on the first organic layer, the black pixel defining layer includes a second opening at a position corresponding to the bending area, and the second opening is filled with an organic layer for the spacer, formed of a same material as the spacer.
