An organic light-emitting device having a resonance structure includes a substrate; a first electrode and a second electrode on the substrate and facing each other; an emission layer between the first electrode and the second electrode; a first hole transport layer between the first electrode and the emission layer; and a second hole transport layer between the first hole transport layer and the emission layer. An electron mobility of the second hole transport layer is 5 times to 100 times greater than an electron mobility of the first hole transport layer, and a thickness of the second hole transport layer corresponds to a resonance distance of a wavelength of emission light of the emission layer.

This application claims priority to and the benefit of Korean Patent Application No. 10-2013-0129558, filed on Oct. 29, 2013, in the Korean Intellectual Property Office, the entire content of which is incorporated herein by reference.
1. Field
One or more aspects according to embodiments of the present disclosure relate to an organic light-emitting device, for example, an organic light-emitting device having a microcavity structure or a resonance structure.
These and/or other aspects will become apparent and more readily appreciated by reference to the following description of certain embodiments when considered together with the accompanying drawings in which:
FIG. 1 is a schematic cross-sectional view of an organic light-emitting device according to an embodiment of the present disclosure;
FIG. 2 is a schematic cross-sectional view of a structure of an organic light-emitting device according to another embodiment of the present disclosure;
Reference will now be made to certain embodiments, examples of which are illustrated in the accompanying drawings, where like reference numerals refer to like elements throughout. As those of ordinary skill in the art would recognize, the described embodiments may be modified in many different ways and, therefore, should not be construed as limiting. Accordingly, the embodiments are described below, by referring to the figures, merely to explain aspects of the present disclosure. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. In the drawings, thicknesses of layers and regions may be exaggerated for illustrative purposes only. Throughout the specification, like reference numerals denote like elements. Also, in the context of the present application, when a first element is referred to as being “on” a second element, it can be directly on the second element or be indirectly on the second element with one or more intervening elements therebetween.
FIG. 1 is a schematic cross-sectional view of an organic light-emitting device 100 according to an embodiment of the present disclosure.
The organic light-emitting device 100 includes a substrate 101, a first electrode 111, a hole injection layer 121, a first hole transport layer 122, a second hole transport layer 123, an emission layer 125, an electron transport layer 127, an electron injection layer 128, and a second electrode 131, which are on one another in the stated order (e.g., they are sequentially formed).
