Embodiment Construction

[0024] Hereinafter, preferred embodiments of the organic electroluminescent device according to the present invention are explained in detail with reference to the accompanying drawings.

[0025] image 3 is a plan view for explaining a part of the organic electroluminescence device according to the present invention. For convenience, only a part of the four columns of anode layers 10 , 20 , 30 and 40 formed on the substrate 100 is shown. Indium zinc oxide (ITO) is preferably used as the anode layer, as will be exemplified below.

[0026] As mentioned above, each column of ITO layers 10 , 20 , 30 and 40 includes two ITO layers 11 , 12 and 21 , 22 . For convenience, only the reference numerals of the ITO layers included in the two columns of ITO layers 10 and 20 are given. Each ITO layer 11, 12, and 21, 22 includes light emitting regions 11A, 12A, 21A, and 22A separated from each other by a predetermined area, and connection regions 11B, 12B, 21B connecting the light emittin...

Abstract

An organic electroluminescent device achieves high clarity by reducing the space between anode layers. The organic electroluminescent device is manufactured by a method in which a cathode layer is provided to intersect an anode layer; an organic layer is formed at each intersecting portion where one cathode layer and two anode layers intersect; and multilayer wiring The portion supplies a driving signal to a first anode layer of a first intersection portion and a second anode layer of a second intersection portion adjacent to the first anode layer.

Description

technical field [0001] The present invention relates to organic electroluminescent devices of the active matrix (AM) and passive matrix (PM) type and methods for their manufacture. In particular, the present invention relates to an organic electroluminescent device capable of achieving high definition and large size by reducing a space between anodes and a method of manufacturing the same. Background technique [0002] Organic electroluminescence is a phenomenon in which excitons are formed in a thin film of an organic (low-molecular or high-molecular) material by the recombination of holes injected from the anode and electrons injected from the cathode, and the energy of the excitons thus formed Produces light of a specific wavelength. The basic structure of an organic electroluminescent device applying this phenomenon and its manufacturing method will be described below. [0003] figure 1 is a plan view of an organic electroluminescent device according to the related ar...
