    Abstract: An organic light emitting device including a plurality of organic layers between a first electrode and an emitting layer, wherein the organic layer includes an electron blocking layer. In one embodiment, a first organic layer, an electron blocking layer, a second organic layer and an emitting layer are formed on the first electrode. The electron blocking layer has a Lowest Unoccupied Molecular Orbital (LUMO) level which is lower than that of the first organic layer. Thus, the electron blocking layer traps excess electrons injected from the emitting layer, thereby improving lifetime characteristics of the OLED.

    Abstract: An organic light emitting diode (OLED) and a method of manufacturing the same. An auxiliary layer comprising a high density metallic compound and an emission layer are formed by a laser induced thermal imaging (LITI) process. The LITI process reduces manufacturing costs and time by eliminating the need for a mask patterning process. The metallic compound has a density of 2 g/cm3 or greater to promote adhesion and improve interfacial planarization. This results in improved luminance uniformity (i.e. luminance mura) between pixels within an OLED display device.
