Embodiment Construction

[0032] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary 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.

[0033] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Like numbers refer to like elements throughout. It will be understood that when an element such as a layer, film, region, or substrate 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 referred to as being "directly on" another element, there are no intervening elements present.

[0034] Now, a display panel for an OLED display according to an embodiment of the present invention and a method of manufacturing the same will be described with refe...

Abstract

A display panel for an organic light emitting display including a plurality of anode electrodes and a cathode electrode that is supplied with a predetermined voltage and includes a first portion facing the anode electrodes and a second portion receiving the predetermined voltage and having a different cross section than the first portion. A plurality of light emitting members is arranged between the anode electrodes and the cathode electrode, and a conductive line transmits the predetermined voltage and contacts the second portion of the cathode electrode.

Description

technical field [0001] The invention relates to a display panel, in particular to a display panel for an organic light emitting diode display. Background technique [0002] Generally, an organic light emitting diode (OLED) display is a self-luminous display device that displays images by exciting organic light emitting materials to emit light. A light emitting element of an OLED display includes an anode (hole injection electrode), a cathode (electron injection electrode), and an organic light emitting layer interposed therebetween. When holes and electrons are injected into the light-emitting layer, they recombine and emit light while transitioning from an excited state to a ground state. In order to enhance light emission, the organic light emitting layer may further include one or more of an electron transport layer (ETL) and a hole transport layer (HTL), and an electron injection layer (EIL) and a hole injection layer (HIL). [0003] An OLED display includes a pluralit...
