Organic light emitting diode display panel

The organic light emitting display panel including a release layer reduction according to an embodiment of the present invention is provided. The opening region and the non-aperture area is defined on the substrate, the reduction of the separation layer such as a triangular wave form, sine wave form, pulse wave form is formed on the bank layer formed on the non-opening region. The substrate is flexible thin film substrate, may be a substrate of a material such as plastic, the stress is dispersed, reduced by the thin film reduction layer applied to the organic light emitting element and the sealing layer leans to the organic light emitting display panel to be used in the organic light emitting display panel is may be minimal delamination of the organic light emitting layer or encapsulation layer.
