Display panel manufacturing method, display panel, and display apparatus

1. A method of manufacturing a display panel having a display and a terminal each formed on a different area on a substrate, comprising:

forming the display on the substrate;

forming a conductive layer of a conductive metal oxide or a metal on an area on the substrate where the terminal is to be formed;

forming a chemical vapor deposition layer of an inorganic compound by a chemical vapor deposition method so that the chemical vapor deposition layer covers the display and comes into contact at least with an upper surface of the conductive layer and to alter the upper surface of the conductive layer; and

removing a portion of the chemical vapor deposition layer by peeling the portion off, the portion being located on the conductive layer, wherein

the conductive layer comprises a conductive metal oxide, and

the forming of the chemical vapor deposition layer includes weakening adhesion strength between the conductive layer and the chemical vapor deposition layer by causing alteration of the conductive metal oxide contained in the upper surface of the conductive layer by reduction thereof using a reducing gas.

2. The method of claim 1 , further comprising:

attaching adhesive tape onto the portion of the chemical vapor deposition layer after performing the formation of the chemical vapor deposition layer and before performing the removing,

wherein in the removing, the portion of the chemical vapor deposition layer is peeled off by pulling the adhesive tape off.

3. The method of claim 1 , further comprising:

forming an atomic layer deposition film on the chemical vapor deposition layer by an atomic layer deposition method after performing the forming of the chemical vapor deposition layer and before performing the removing.

4. The method of claim 3 , further comprising:

attaching adhesive tape onto a portion of the atomic layer deposition film after performing the forming of the atomic layer deposition film and before performing the removing, the portion being located above the conductive layer, wherein

in the removing, the portion of the chemical vapor deposition layer and the portion of the atomic layer deposition film are peeled off by pulling the adhesive tape off.

5. The method of claim 1 ,

wherein the conductive metal oxide is ITO or IZO.

6. The method of claim 1 ,

wherein the reducing gas is SiN or SiH 4 .

7. The method of claim 1 ,

wherein in forming of the chemical vapor deposition layer, a damaged layer is formed on the upper surface of the conductive layer simultaneously with the chemical vapor deposition layer.

8. A method of manufacturing a display panel having a display and a terminal each formed on a different area on a substrate, comprising:

forming the display on the substrate;

forming a conductive layer of a conductive metal oxide or a metal on an area on the substrate where the terminal is to be formed;

forming a chemical vapor deposition layer of an inorganic compound by a chemical vapor deposition method so that the chemical vapor deposition layer covers the display and comes into contact at least with an upper surface of the conductive layer and to alter the upper surface of the conductive layer; and

removing a portion of the chemical vapor deposition layer by peeling the portion off, the portion being located on the conductive layer, wherein

the conductive layer comprises a conductive metal oxide, and

the forming of the chemical vapor deposition layer includes forming a damaged layer by causing alteration of the conductive metal oxide contained in the upper surface of the conductive layer by reduction thereof using a reducing gas, the chemical vapor deposition layer and the damaged layer being formed simultaneously.

9. The method of claim 8 ,

wherein the forming of the damaged layer weakens adhesion strength between the conductive layer and the chemical vapor deposition layer.
