Abstract
Disclosed is an OLED device capable of reducing the number of manufacturing processes to apply a micro-cavity structure, and a method for manufacturing the same, wherein the OLED device may include a unit pixel having first to third subpixels, wherein each of the first to third subpixels includes a first electrode, an organic light emitting layer disposed on the first electrode, a second electrode disposed on the organic light emitting layer and formed of a transparent metal material, an encapsulation film for covering the second electrode, and a semi-transmissive electrode disposed on the encapsulation film, wherein a distance between the first electrode and the semi-transmissive electrode in the first subpixel, a distance between the first electrode and the semi-transmissive electrode in the second subpixel, and a distance between the first electrode and the semi-transmissive electrode in the third subpixel are different from one another.
