Abstract

A light emitting display device is disclosed that includes: a display panel having a plurality of pixel circuits arranged in a matrix; a plurality of power supply lines coupled to the pixel circuits, for applying a first voltage; and a conductive bar having one terminal coupled to a power for supplying the first voltage, and connected to at least one surface of the display panel, to transmit the first voltage to the power supply lines.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2003-0086118 filed on November 29, 2003 in the Korean Intellectual Property Office, the contents of which are hereby incorporated by reference. technical field [0002] The invention relates to a light emitting display device. More specifically, the present invention relates to an organic EL (Electro Luminescence) display device that uniformly applies a power supply voltage to a display panel. Background technique [0003] Generally, an organic EL display electrically excites a phosphorous organic compound to emit light, and an organic EL display voltage-programs or current-programs an N×M matrix of organic light-emitting units to display images. Each organic light-emitting unit includes an anode (ITO), an organic thin film, and a cathode layer (metal). The organic thin film has a multilayer structure including EML (Emission Layer), ETL (Electron Transport Layer), and HTL (Hole Transport Layer) f...
