Organic light emitting display device including touch sensor

A display device, comprising:

• a first sub-pixel, a second sub-pixel, and a third sub-pixel, each of the first, the second, and the third sub-pixel including a respective transistor and light emitting source;
• a substrate overlying on the transistor and the light emitting source of each of the first, the second, and the third sub-pixel;
• and
• a touch sensor disposed on the substrate,
• wherein the touch sensor includes:
• a plurality of lower electrodes spaced apart from each other, each of the lower electrodes disposed on the substrate;
• a plurality of upper electrodes spaced apart from each other, each of the upper electrodes positioned over a corresponding one of the lower electrodes;
• a first color control layer located between a first lower electrode of the plurality of lower electrodes and a first upper electrode of the plurality of upper electrodes, the first color control layer emits light corresponding to a color of the first sub-pixel;
• a second color control layer located between a second lower electrode of the plurality of lower electrodes and a second upper electrode of the plurality of upper electrodes, the second color control layer emits light corresponding to a color of the second sub-pixel;
• and
• a third color control layer located between a third lower electrode of the plurality of lower electrodes and a third upper electrode of the plurality of upper electrodes, the third color control layer emits light corresponding to a color of the third sub-pixel;
• wherein the first, second and third color control layers have different thicknesses to emit lights having different wavelengths.
