1. A light emitting display device comprising:
a substrate comprising first subpixels and second subpixels;
a plurality of thin film transistors including a first thin film transistor and a second thin film transistor;
a first transparent electrode and a second transparent electrode at the first subpixels and the second subpixels, respectively;
a first reflective electrode on the first transparent electrode and connected to the first thin film transistor via the first transparent electrode, and a second reflective electrode on the second transparent electrode and connected to the second thin film transistor via the second transparent electrode;
a first optical compensation layer on the first reflective electrode;
a first anode to contact the first optical compensation layer, the first optical compensation layer between the first anode and the first reflective electrode;
a second anode to contact the second reflective electrode;
a first unit having at least one first stack comprising a first common layer, a first emission layer to emit light with a first wavelength, and a second common layer, which are sequentially stacked on the first anode;
a second unit having at least one second stack comprising the first common layer, a second emission layer to emit light with a second wavelength that is less than the first wavelength, and the second common layer, which are sequentially stacked on the second anode; and
a cathode on the first unit and the second unit.
