Organic light emitting device

#This application claims the benefit of Korean Patent Application No. 10-2013-0126452, filed on Oct. 23, 2013, which is hereby incorporated by reference for all purposes as if fully set forth herein.

#Field of the Invention

#The present invention relates to an organic light emitting device, and more specifically, to an organic light emitting device including a hole connection layer between light emitting layers and method for manufacturing the same.

#The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention. In the drawings:

#FIG. 1 is a cross-sectional view showing an organic light emitting device according to the related art;

#FIG. 2 is a view illustrating an organic light emitting device according to an embodiment of the present invention;

#Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers may be used throughout the drawings to refer to the same or like parts.

#FIG. 2 is a view illustrating an organic light emitting device according to an embodiment of the present invention; FIG. 3 is a diagram illustrating an energy band of an organic light emitting device according to an embodiment of the present invention; and FIG. 4 is a view illustrating an organic light emitting device according to another embodiment of the present invention.

#Referring to FIG. 2, an organic light emitting device 100 according to an embodiment of the present invention may be an organic light emitting device emitting red, green, and blue light wavelengths. In the present embodiment, three sub-pixels constitute one unit pixel, and the three sub-pixels include a red light emitting part 105R which emits a red light, a green light emitting part 105G which emits a green light, and a blue light emitting part 105B which emits a blue light, thereby capable of displaying full colors. The organic light emitting device 100 further includes a first light emitting layer 150R, a second light emitting layer 150G, and a third light emitting layer 150B between first electrodes 120R, 120G, and 120B on a substrate 110 and a second electrode 190.
