Embodiment Construction

[0025] Reference will now be made in detail to the preferred embodiments, examples of which are illustrated in the accompanying drawings.

[0026] figure 2 is a circuit diagram showing an OELD according to the present invention. Such as figure 2 As shown, the OELD includes a gate line "GL", a data line "DL", a power line "PL", a switching thin film transistor (TFT) "STr", a storage capacitor "StgC", a driving TFT "DTr" and an organic electroluminescent diode "E". The gate line 'GL' and the data line 'DL' cross each other, and the power line 'PL' is formed parallel to the data line 'DL'. The switching TFT "STr" is formed at a crossing portion of the gate line "GL" and the data line "DL". The driving TFT "DTr" is electrically connected to the switching TFT "STr".

[0027] The driving TFT "DTr" is electrically connected with the organic electroluminescence diode "E". More specifically, the first electrode of the organic electroluminescent diode "E" is connected to the dra...

Abstract

An organic electroluminescent device including a first red sub-pixel region, a first green sub-pixel region and a deep blue sub-pixel region in a first pixel region; and a second red sub-pixel region, a second green sub-pixel region and a sky blue sub-pixel region in a second pixel region adjacent to the first pixel region, wherein each of the first and second red sub-pixel regions includes a first electrode, a red organic emission material pattern and a second electrode, each of the first and second green sub-pixel regions includes the first electrode, a green organic emission material pattern and the second electrode, wherein the deep blue sub-pixel region includes the first electrode, a deep blue organic emission material pattern and the second electrode, and the sky blue sub-pixel region includes the first electrode, a sky blue organic emission material pattern and the second electrode, and wherein an unit pixel displaying an image includes at least one of the deep blue sub-pixel region and the sky blue sub-pixel region with the second red sub-pixel region and the second green sub-pixel region.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2010-0083631 filed Aug. 27, 2010, which is hereby incorporated herein. technical field [0002] The present invention relates to an organic electroluminescence device (OELD), and more particularly, to an OELD having advantages in aperture ratio, color reproduction and resolution. Background technique [0003] Although cathode ray tubes are widely used in display devices, however, flat panel displays such as plasma display panels (PDPs), liquid crystal display devices (LCDs), and OELDs are also developed and used. [0004] OELD is a self-illuminating type and does not require a backlight unit. Therefore, OELDs are light in weight and low in power consumption. In addition, OELD has excellent characteristics such as viewing angle, contrast ratio and response time. In particular, the OELD is manufactured by a simpler process, and thus the production cost of the OELD is low. Recently, flexible OELDs...
