Abstract
Provided is an electroluminescence display device. The electroluminescence display device includes a display area, a non-display area positioned the outer periphery of the display area, a thin film transistor in the display area, and a power supply line in the non-display area and connected to the thin film transistor. The power supply line includes a first part and a second part separated from each other, and a third part connected to the first part and the second part, and also includes a first layer formed along an edge portion of the power supply line and covering the edge portion of the power supply line.
Claims23
An electroluminescence display device comprising:
- a display area;
- a non-display area positioned adjacent to an outer periphery of the display area;
- a pad part in the non-display area;
- a thin film transistor in the display area;
- a power supply line in the non-display area and connected to the thin film transistor, the power supply line including:
- a first part connected to the pad part,
- a second part spaced apart from the first part along a first direction, and
- a third part extending along the first direction and connected between the first part and the second part, the third part having a width along a second direction that is substantially the same as a width along the second direction of at least one of the first part or the second part, the second direction being transverse to the first direction;
- a first layer covering, and in direct contact with, first, second, and third edges of the second part of the power supply line, the first edge faces the first part of the power supply line along the first direction, and the second and third edges are opposite one another along the second direction, a central portion of a surface of the second part of the power supply line being uncovered by the first layer between the first, second, and third edges;
- a second layer covering the first part of the power supply line, the second layer being in direct contact with, and covering, an edge of the first part of the power supply line that faces the first edge of the second part of the power supply line, the second layer spaced apart from the first layer along the first direction by a gap;
- and
- a protective layer on the first layer and the second layer, at least a portion of the protective layer disposed in the gap and extending in the gap from the first layer to the second layer.

An electroluminescence display device, comprising:
- a substrate including a display area and a non-display area;
- a pad part in the non-display area;
- a power supply line positioned in the non-display area and connected to a thin film transistor positioned in the display area, the power supply line including:
- a first part adjacent to the pad part,
- a second part adjacent to the thin film transistor in the display area, and
- a third part between the first part and the second part, the third part including a connection part which connects the first part and the second part;
- a protective layer configured to cover at least a part of the power supply line;
- and
- an anti-moisture permeation pattern formed along edge portions of the power supply line, the anti-moisture permeation pattern in direct contact with a surface of the second part of the power supply line and covering opposite first and second edge portions of the second part of the power supply line, the first and second edge portions being spaced laterally apart from one another along a width of the second part of the power supply line, a central portion of the surface of the second part of the power supply being uncovered by the anti-moisture permeation pattern along the width of the second part of the power supply from the first edge portion to the second edge portion,
- wherein the protective layer directly contacts the surface of the power supply line from a first portion of the anti-moisture permeation pattern that covers the first edge portion of the power supply line to a second portion of the anti-moisture permeation pattern that covers the second edge portion of the power supply line, the protective layer directly contacting and completely covering the central portion of the surface of the second part of the power supply line.
