Abstract: A display device is disclosed, which may reduce an interval between subpixels and maximize a light emission area. The display device comprises a substrate provided with a first subpixel and a second subpixel arranged to adjoin the first subpixel, a first electrode provided in each of the first subpixel and the second subpixel on the substrate, including a first material, and an oxide insulating film provided to cover at least a portion of a side of the first electrode and made of a second material. The first material is a metal material, and the second material is an oxide of the first material.

Abstract: Disclosed are an organic light emitting display device and a method of manufacturing the same, in which in a white organic light emitting device, an adverse influence of a leakage current leaked through an organic light emitting layer is minimized on an adjacent pixel. The organic light emitting display device includes a first electrode on a substrate, a bank covering a portion of the first electrode, a bank hole provided in the bank, an organic light emitting layer on the first electrode and the bank, and a second electrode on the organic light emitting layer.
