Claim:
1. An organic light emitting device, comprising: a substrate; a thin film transistor on a first surface of the substrate; a pixel electrode electrically connected to the thin film transistor; a partition defining an opening on the pixel electrode; an organic light emitting layer including a portion disposed in the opening; a common electrode on the organic light emitting layer; a first layer on the common electrode, wherein the first layer includes a first portion and a second portion, the first portion overlaps both the opening and the organic light emitting layer in a first direction perpendicular to the first surface of the substrate, and the second portion overlaps the partition in the first direction; a second layer on the first layer, wherein the second layer includes a third portion and a fourth portion, the third portion overlaps the first portion in the first direction, and the fourth portion overlaps the second portion in the first direction; and a touch sensor on the second layer, wherein: a maximum distance between an upper surface of the first portion of the first layer and the first surface of the substrate is less than a maximum distance between an upper surface of the second portion of the first layer and the first surface of the substrate, and a maximum thickness of the third portion of the second layer is greater than a maximum thickness of the fourth portion of the second layer.
