Abstract

An organic light emitting display panel and an organic light emitting display device are disclosed. Specifically, there may be provided an organic light emitting display panel and an organic light emitting display device capable of preventing a reduction in the emission area due to the repair area by including a thin film transistor including a first active layer disposed in the first emission area, a second active layer overlapping the second emission area of the first substrate, electrically connected to the thin film transistor, and disposed on the same layer as the first active layer, and a light emitting element electrically connected to the thin film transistor and including an anode electrode, a light emitting layer, and a cathode electrode disposed in the first emission area, wherein the light emitting layer and the cathode electrode are disposed on the second active layer in the second emission area.
