Abstract

Disclosed are an organic light emitting display, which may achieve weight reduction and slimming, and a method of fabricating the same. An encapsulation part of the organic light emitting display includes a plurality of inorganic encapsulation layers and at least one organic encapsulation layer disposed between the inorganic encapsulation layers, and a plurality of touch electrodes disposed on one of the inorganic encapsulation layers and the at least one organic encapsulation layer of the encapsulation part, each touch electrode having electrically independent self capacitance, thereby achieving weight reduction and slimming of the organic light emitting display.

Dependent claims

A display device comprising:

light emitting devices disposed on a substrate;
an encapsulation layer structure disposed on the light emitting devices:
a touch sensor comprising:
a plurality of touch sensing electrodes disposed on the encapsulation layer structure along a first direction;
and
a plurality of touch driving electrodes on the encapsulation layer structure and in a same plane as the plurality of touch sensing electrodes, the plurality of touch driving electrodes disposed along the first direction and in parallel with the plurality of touch sensing electrodes;
and
at least one routing line disposed between the encapsulation layer structure and the touch sensor and connected to the touch sensor, wherein the at least one routing line is running along at least one sidewall of the encapsulation layer structure.
