Abstract

A display device includes a thin film transistor formed on a first insulating substrate, a first electrode electrically connected with the thin film transistor, an emission layer formed on the first electrode, a second electrode formed on the emission layer, an auxiliary electrode shaped like a mesh to at least partially expose the first electrode, the auxiliary electrode being electrically connected with the second electrode and receiving a common voltage therefrom, and a second insulating substrate placed on the auxiliary electrode. The exemplary embodiments of a display device, and a method of manufacturing the same, according to the present invention can apply a common voltage efficiently throughout the display and have an improved contrast ratio.

Description

[0001] Related Application Cross Reference [0002] This application claims the benefit of Korean Patent Application No. 2005-0109142 filed on November 15, 2005 and Korean Patent Application No. 2006-0090046 filed on September 18, 2006, the entire contents of which are hereby incorporated by reference . technical field [0003] The present invention relates to a display device and a method of manufacturing the same, and more particularly, to a display device and method of manufacturing the same that can efficiently apply a common voltage to the entire display and have improved contrast. Background technique [0004] Among flat-panel displays, organic light-emitting diode ("OLED") displays have recently become popular due to their low-voltage drive, thinness and lightness, wide viewing angle, relatively short response time, and various other attractive and desirable features. And much attention. OLED displays are classified into a passive matrix type and an active matrix ty...
