Abstract:
The present invention provides a stack type organic electroluminescence display apparatus which can be structured to be an active matrix type. The organic electroluminescence display apparatus of the active-matrix driving system includes: a display region having a plurality of pixels each of which includes at least two subpixels, wherein the subpixels have three or more light-emitting devices stacked thereon each of which is configured by sandwiching between electrodes an organic layer including an emission layer, and any of the emission layers emits a light of different colors from each other and is commonly formed in all pixels; and a circuit for applying voltage to between the electrodes of the light-emitting device, wherein at least one light-emitting device among the stacked light-emitting devices is nonemission-treated.
