Organic light emitting display device and method of manufacturing the same using a solution process

摘要

An organic light emitting display device includes a substrate in which a first pixel area and a second pixel area different from each other are defined, a first electrode, a pixel defining layer, a common layer, a first surface processing layer, a second surface processing layer, a first liquid solution layer, a second liquid solution layer, and a second electrode. The first surface processing layer has a first width and is correspondingly included in the first pixel area. The second surface processing layer has a second width different from the first width and is correspondingly included in the second pixel area. The first liquid solution layer has the first width, and the second liquid solution layer has the second width. The first and second liquid solution layers have the same volume and different thicknesses.
