Problems solved by technology

Smaller currents cause the pixel associated with it to emit dimmer light, creating interference, which is exacerbated when the number of pixels expected to emit brighter light increases

Embodiment Construction

[0043] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

[0044]In the drawings, the thicknesses of layers and regions are exaggerated for clarity. The same reference numerals refer to the same parts throughout. It will be understood that when an element such as a layer, film, region, substrate, or panel is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is described as being "directly on" another element, there are no intervening elements present.

[0045] Hereinafter, an organic electroluminescence display and a method of manufacturing the same according to an embodiment of the present invention will be descr...

Abstract

According to an aspect of the present invention, an organic electro-luminescence display panel is provided, which includes: an insulating substrate; a polysilicon layer formed on the substrate; a first insulating layer formed on the polysilicon layer; a gate wire formed on the first insulating layer; a second insulating layer formed on the gate wire; a data wire formed on the second insulating layer and including first and second portions; a pixel electrode connected to the first portion of the data wire; a partition defining an area on the pixel electrode; an organic light emitting member formed in the area on the pixel electrode; a common electrode formed on the light emitting member; and a planar supply voltage electrode disposed between the pixel electrode and the substrate and connected to the second portion of the data wire.

Description

[0001] This application is a divisional application of a patent application with an application date of December 11, 2003 and an application number of No. 200310124911.7 entitled "Organic Electroluminescence Display Panel". technical field [0002] The invention relates to an organic electroluminescence display panel. Background technique [0003] Generally, an organic electroluminescent (EL) display is a self-emissive display device that displays an image by exciting an emissive organic material to emit light. The organic EL display includes an anode (hole injection electrode), a cathode (electron injection electrode), and an organic light emitting layer sandwiched therebetween. When holes and electrons are injected into the light-emitting layer, they recombine and annihilate in pairs to generate light. The light emitting layer also includes an electron transport layer (ETL) and a hole transport layer (HTL) and an electron injection layer (EIL) and a hole injection layer (...
