Abstract

A mother glass is disclosed. The mother glass includes a plurality of organic electro luminescence arrays having a scan pad and a data pad. The plurality of organic electro luminescence arrays are arranged in a matrix type. The mother glass also includes: a non-array area, arranged between the organic electro luminescence arrays and an edge area located at an exterior of the arrangement of the matrix; at least one positive shorting bar formed at the edge area; at least one negative shorting bar formed at the edge area; a first line formed at the non-array area to electrically connect the data pad to the positive shorting bar; and a second line formed at the non-array area to electrically connect the scan pad to the negative shorting bar.

Claims (20)

1. A method of fabricating an organic electro luminescence display device, comprising:

providing a mother glass including a plurality of organic electro luminescence arrays having a scan pad and a data pad, wherein the plurality of organic electro luminescence arrays are arranged in a matrix type, a non-array area, arranged between the organic electro luminescence arrays arranged in the matrix type, and an edge area located at an exterior of the arrangement of the matrix;

forming at least more than one positive shorting bar at the edge area to supply with a positive voltage, and forming at least more than one negative shorting bar at the edge area to supply with a negative voltage; and

forming a first line at the non-array area to electrically connect the data pad, formed in each of organic electro luminescence arrays, to the positive shorting bar, and forming a second line at the non-array area to electrically connect the scan pad, formed in each of organic electro luminescence arrays, to the negative shorting bar.

2. The method according to claim 1 , further comprising forming a first common line connected to the first line and commonly connected to each data pad, and a second common line connected to the second line and commonly connected to each scan pad.

3. The method according to claim 1 , further comprising:

forming a dummy insulating film at a cross both the first line and the second line to electrically insulate the first line from the second line; and

forming a first metal pattern on the dummy insulating film to electrically connect any one of the fist line and the second line.

4. The method according to claim 3 , wherein the organic electro luminescence array includes:

a first electrode;

an insulating film partially exposing the first electrode to define a light-emitting area; and

a second electrode formed at the light-emitting area, and

wherein the dummy insulating film is simultaneously formed of the same material as the insulating film and the first metal pattern is simultaneously formed of the same material as the second electrode.

5. A method of fabricating an organic electro luminescence display device, using a mother glass including a plurality of organic electro luminescence arrays forming row and column and having a scan pad and data pad, and having a row direction non-array area arranged between the organic electro luminescence arrays of an adjacent row, a column direction non-array area arranged between the organic electro luminescence arrays of an adjacent column, a left column direction non-array area arranged at a left side of the organic electro luminescence arrays of the far left column and a right column direction non-array area arranged at a right side of the organic electro luminescence arrays of the far right column, comprising:

forming a plurality of positive shorting bars in at least one area of the left non-array area and the right non-array area as many as the number of rows of the organic electro luminescence arrays to supply with a positive voltage;

forming a plurality of negative shorting bars in at least one area of the left non-array area and the right non-array area as many as the number of rows of the organic electro luminescence arrays to supply with a negative voltage; and

forming a plurality of first lines along the row direction non-array area located at an upper part of each row of the organic electro luminescence arrays to electrically connect the data pad, formed in each of the organic electro luminescence arrays, to the positive shorting bar, and forming a plurality of second lines along the row direction non-array area located at a lower part of each row of the organic electro luminescence arrays to electrically connect the scan pad, formed in each of the organic electro luminescence arrays, to the negative shorting bar.

6. The method according to claim 5 , further comprising forming a first common line at the non-array area to be connected to the first line and to be commonly connected to each data pad, and forming a second common line connected to the second line and commonly connected to each scan pad.

7. The method according to claim 1 or claim 5 , wherein the positive shorting bar, the second shorting bar, the first line and the second line are simultaneously patterned by one mask.

8. The method according to claim 2 or claim 6 , wherein the positive shorting bar, the second shorting bar, the first line, the second line, the first common line and the second common line are simultaneously patterned by one mask.
