Abstract

An electro-luminescence display device includes a connection film being connected to a driving circuit, a pad connected to the connection film in order to supply a driving signal from the driving circuit to a signal line formed on a substrate, a conductive film for connecting the connection film to the pad, and a plurality of dummy pads. Each dummy pad includes a transparent conductive layer. At least one of the dummy pads is formed to expose the transparent conductive layer in order to test an adhesive level of the connection film and the pad by the conductive film.

Claims (9)

1. An electro-luminescence display device comprising:

a connection film being connected to a driving circuit;

a pad connected to the connection film in order to supply a driving signal from the driving circuit to a signal line formed on a substrate;

a conductive film for connecting the connection film to the pad; and

a plurality of dummy pads, each dummy pad including a transparent conductive layer, wherein at least one of the dummy pads is formed to expose the transparent conductive layer in order to test an adhesive level of the connection film and the pad by the conductive film.

2. The device according to claim 1 , wherein each of the dummy pads includes: an opaque conductive layer formed on the transparent conductive layer.

3. The device according to claim 1 , wherein at least one of the dummy pads includes an alignment mark for aligning the connection film and the pad.

4. The device according to claim 2 , wherein any one of the dummy pads has a single-layer structure of the transparent conductive layer, and the remaining dummy pads have a double-layer structure of the transparent conductive layer and the opaque conductive layer.

5. The device according to claim 2 , wherein the opaque conductive layer exposes at least a portion of the transparent conductive layer.
