Abstract
An electroluminescent display device includes a substrate on which a display area and a non-display area are defined. A thin film transistor is in the display area on the substrate. A light-emitting diode is connected to the thin film transistor and includes a first electrode, a light-emitting layer and a second electrode. A first link line is disposed in the non-display area and applies a first voltage to the first electrode. A second link line is spaced apart from the first link line in the non-display area. A conductive pattern is disposed in the non-display area and is connected to the second electrode to apply a second voltage. The conductive pattern has an opening corresponding to the first link line.

An electroluminescent display device, comprising:
- a substrate on which a display area and a non-display area are defined;
- a thin film transistor in the display area on the substrate;
- a light-emitting diode connected to the thin film transistor and including a first electrode, a light-emitting layer and a second electrode;
- a first link line disposed in the non-display area and configured to apply a first voltage to the first electrode;
- a second link line spaced apart from the first link line in the non-display area;
- and
- a conductive pattern disposed in the non-display area and connected to the second electrode to apply a second voltage, the conductive pattern having an opening corresponding to the first link line.
An electroluminescent display device, comprising:
- a sub pixel in a display area of the display device, the sub pixel including a thin film transistor coupled to a light-emitting diode having a first electrode and a second electrode;
- a first link line in a non-display area of the display device, the first link line configured to provide a first voltage to the first electrode;
- a second link line spaced apart from the first link line in the non-display area, the second link line configured to provide a second voltage that is less than the first voltage;
- and
- a conductive pattern overlapping the first and second link lines in the non-display area, the conductive pattern configured to provide a reference voltage to the second electrode and including an opening corresponding to the first link line.
A method, comprising:
- forming thin film transistors and light-emitting diodes in a display area of a substrate of an electroluminescent display, each light-emitting diode including a first electrode, a light-emitting layer and a second electrode;
- forming a first link line in a non-display area surrounding the display area, the first link line configured to provide a first voltage to the first electrode;
- forming a second link line spaced apart from the first link line in the non-display area;
- forming a conductive pattern in the non-display area overlapping the first and second link lines and coupled to the second electrode;
- and
- forming an opening in the conductive pattern over the first link line to provide a first overlap of the conductive pattern with the first link line that is smaller than a second overlap of the conductive pattern with the second link line.
