1. An organic light emitting display device comprising:

  • a display panel having a display element layer and an encapsulation layer on the display element layer, wherein the display element layer comprises;

    a plurality of pixels including a plurality of light emitting layers between pixel electrodes and an opposed electrode; and

    a plurality of signal lines and a plurality of thin film transistors, the encapsulation layer comprises at least one inorganic insulating layer and an organic insulating layer;

    a substrate on the encapsulation layer;

    first touch electrodes arranged in a first direction on the substrate;

    a dielectric layer on the first touch electrodes; and

    second touch electrodes arranged in a second direction on the dielectric layer,wherein the display panel has a first portion, a second portion and a third portion, the first portion and the second portion are curved, and the third portion between first portion and second portion is substantially flat,wherein the substrate has a fourth portion, a fifth portion and a sixth portion, the fourth portion and the fifth portion are curved, and the sixth portion between the fourth portion and the fifth portion is substantially flat,wherein the first portion substantially entirely overlaps with the fourth portion in a plan view,wherein the second portion substantially entirely overlaps with the fifth portion in the plan view,wherein the third portion substantially entirely overlaps with the sixth portion in the plan view,wherein the second touch electrodes are alternately arranged with the first touch electrodes so that the second touch electrodes do not overlap the first touch electrodes in the plan view, andwherein the first touch electrodes and the second touch electrodes have a substantially quadrangular shape.
