Abstract
Disclosed is a light emitting display device including a first anode at a red subpixel, a second anode at a white subpixel, a third anode at a blue subpixel, and a fourth anode at a green subpixel, an intermediate layer on the first anode, the second anode, the third anode, and the fourth anode, the intermediate layer comprising four or more stacks and a charge generation layer between the stacks and a cathode on the intermediate layer. Each of the first anode and the second anode may have a lower refractive index than each of the third anode and the fourth anode for light of the same wavelength.

A light emitting display device comprising:
- a substrate including a red subpixel, a white subpixel, a blue subpixel, and a green subpixel;
- a first anode at the red subpixel, a second anode at the white subpixel, a third anode at the blue subpixel, and a fourth anode at the green subpixel;
- an intermediate layer on the first anode, the second anode, the third anode, and the fourth anode, the intermediate layer comprising four or more stacks and a charge generation layer between the stacks;
- and
- a cathode on the intermediate layer,
- wherein each of the first anode and the second anode has a lower refractive index than each of the third anode and the fourth anode for light of the same wavelength.
