Abstract:
1. An organic light emitting display device, comprising: a substrate; a thin film transistor (TFT) formed on the substrate; a first insulating layer covering the TFT; a first electrode formed on the first insulating layer and electrically connected to the TFT; a second insulating layer formed on the first insulating layer so as to cover the first electrode, the second insulating layer having an opening to expose a portion of the first electrode; an organic layer formed on a portion of the second insulating layer and the first electrode; a second electrode formed on the second insulating layer and the organic layer, the second electrode composed of a first region and a second region; a capping layer formed on the first region of the second electrode, the capping layer having first edges; and a third electrode formed on the second region of the second electrode, the third electrode having second edges whose side surfaces contact side surfaces of the first edges of the capping layer; the third electrode and the capping layer not overlapping each other in a direction perpendicular to a major surface of the substrate, or the third electrode overlapping the capping layer in the direction perpendicular to the major surface of the substrate and including a first portion contacting the first edges of the capping layer and a second portion connected to the first portion, and a thickness of the first portion of the third electrode being greater than a thickness of the second portion of the third electrode.
