A display device includes a substrate, a passivation layer on the substrate and including an area having a first thickness and an area having a second thickness less than the first thickness, a first electrode on the passivation layer and including at least two sub-electrodes spaced apart from each other by a slit having two ends, a light emitting layer on the first electrode, and a second electrode on the light emitting layer. Both ends of the slit are in one the area of the passivation layer having the second thickness.
