Problems solved by technology

In the case of using a deposition method, the solvent used for the intermediate layer, for example, the solvent used for the solution of HTL, dissolves EML during the deposition process, deteriorating the interface characteristics
In addition, by utilizing both the nozzle printing method and the deposition method, input costs may increase, a large space for equipment may be required, and it may be difficult or impossible to arrange in-line based equipment

Abstract

In an organic light-emitting display device and a method of manufacturing the organic light-emitting display device, the method includes forming thin film transistors (TFTs) on a substrate; and forming organic light emitting diodes (OLEDs), each of the OLEDs including a first electrode having a portion exposed by a pixel defining layer (PDL) on the TFTs, an organic layer on the exposed portion of the first electrode and including an emission layer (EML) configured to emit light having a respective one of a plurality of colors, and a second electrode on the organic layer. The EML is formed in each of a sub-pixel region with one color and other sub-pixel regions with other colors that are formed by forming openings in the PDL. A solution supply unit for sub-pixel region that communicates with the sub-pixel region with one color is formed in the sub-pixel region with one color.

Description

[0001] This application claims priority and benefit from Korean Patent Application No. 10-2011-0137408 filed in the Korean Intellectual Property Office on December 19, 2011, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to an organic light emitting display device and a method for manufacturing the organic light emitting display device. Background technique [0003] In general, organic light-emitting display devices can be applied to mobile devices (such as digital cameras, video cameras, camcorders, portable information terminals, smart phones, ultra-thin notebooks, desktop personal computers, and flexible display devices) or electronic / electrical devices (such as ultra-thin TVs) machine) display device. [0004] An organic light emitting display device has a stack structure in which an emission layer (EML) is interposed between an anode and a cathode. However, it is difficult to obtain hi...
