Abstract
An organic light emitting display device includes: a substrate including a first sub-pixel, a second sub-pixel, and a third sub-pixel; a driving thin film transistor and a light emitting diode provided at each of the first to third sub-pixels; an encapsulation substrate configured to cover the driving thin film transistor and the light-emitting diode; and a touch sensor disposed on the encapsulation substrate, wherein the touch sensor includes: a lower electrode disposed on the encapsulation substrate; a first color control layer disposed on the lower electrode to correspond to the first sub-pixel; a second color control layer disposed on the lower electrode to correspond to the second sub-pixel; a third color control layer disposed on the lower electrode to correspond to the third sub-pixel; and an upper electrode disposed on the first to third color control layers, wherein the first to third color control layers have different thicknesses.
