The intermediate layer 220 includes an emission layer 222 on the pixel electrode 210 exposed through the opening of the pixel-defining film 2190. The emission layer 222 may include a high molecular weight organic material or a low molecular weight organic material that emits light of a predetermined color. In an embodiment, the intermediate layer 220 may include a first functional layer 221 located under the emission layer 222 and/or a second functional layer 223 located over the emission layer 222 as shown in
The first functional layer 221 may have a single or multi-layer structure. For example, when the first functional layer 221 is formed of a high molecular weight material, the first functional layer 221 that is a hole transport layer (HTL) having a single-layer structure may be formed of poly(3,4-ethylenedioxythiophene) (PEDOT) or polyaniline (PANI). When the first functional layer 221 is formed of a low molecular weight material, the first functional layer 221 may include a hole injection layer (HIL) and a hole transport layer (HTL).
The second functional layer 223 is optional. For example, when each of the first functional layer 221 and the emission layer 222 is formed of a high molecular weight material, in order to improve the characteristics of the OLED, it is preferable to form the second functional layer 223. The second functional layer 223 may have a single or multi-layer structure. The second functional layer 223 may include an electron transport layer (ETL) and/or an electron injection layer (EIL).
