Claim Text:
1. An organic light emitting device comprising: a substrate; a thin film transistor disposed on a first surface of the substrate; an organic light emitting element connected to the thin film transistor and configured to receive a data voltage; a plurality of encapsulation thin films disposed on the organic light emitting element and encapsulating the organic light emitting element, wherein the plurality of encapsulation thin films include a first portion overlapping the organic light emitting element in a direction perpendicular to the first surface of the substrate and a second portion connected to the first portion and including the same encapsulation thin films as the first portion, wherein a maximum distance between an upper surface of the first portion and the first surface of the substrate is less than a maximum distance between an upper surface of the second portion and the first surface of the substrate; a planarization layer disposed on the plurality of encapsulation thin films, wherein a maximum thickness of the planarization layer corresponding to the first portion is greater than a maximum thickness of the planarization layer corresponding to the second portion; and a touch conductive layer disposed on a planar surface of the planarization layer.
