Embodiment Construction

[0025] Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. However, the invention may be carried out in various ways and it is not intended to limit the invention to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will be sufficient to convey the scope of the invention to those skilled in the art.

[0026] figure 2 is a structural view showing an OELD device according to an embodiment of the present invention. figure 2 The illustrated OELD device uses a separate RGB layer structure to form a full color image. The OELD device is a bottom emission type OELD device in which light for displaying images is generated at the bottom of the OELD device and supplied upward.

[0027] refer to figure 2 , the OELD device includes a plurality of first electrodes 100 extending in a first direction; and a plurality of second ...

Abstract

The invention discloses an organic electroluminescent display device, comprising: a plurality of first electrodes formed on a substrate; a plurality of second electrodes formed on the substrate and below the plurality of first electrodes; formed an organic light emitting layer between the plurality of first electrodes and the plurality of second electrodes; and a color filter layer formed on the substrate, wherein the color filter layer includes a red filter , a green filter, a blue filter and a white filter.

Description

technical field [0001] The present invention relates to an organic electroluminescent display device, and in particular to an organic electroluminescent display device using a four-color system to form a color image. Background technique [0002] An organic electro-luminescent display (OELD) such as an active matrix organic light emitting diode (AMOLED) may include: an anode comprising an anode made of, for example, indium tin oxide A transparent electrode made of (ITO); a cathode including a metal electrode having a low work function; and an organic light-emitting layer including an organic thin layer disposed between the anode and the cathode. [0003] When a direct current is applied to the OELD device, holes are emitted from the anode and injected into the organic light emitting layer, and electrons are emitted from the cathode and injected into the organic light emitting layer . The holes and electrons recombine within the organic light emitting layer to emit light. ...
