Abstract

An organic light-emitting display device having a touch sensor is discussed. The organic light-emitting display device includes a touch sensor formed in a single-layer structure and disposed on an encapsulation unit disposed on a light-emitting element. First and second bridges and first and second touch electrodes included in the touch sensor having a single-layer structure are formed of the same material as each other in the same plane, e.g., on the uppermost layer of the encapsulation unit, thereby simplifying the structure thereof and reducing costs.
