A method for forming an alignment key flexible display comprising:
- coating a photo resist layer on a substrate defined display area and non-display area, wherein the non-display area has an alignment key forming part, wherein the substrate is flexible and made of opaque metal;
- forming a photo resist pattern by selectively removing the photo resist layer to expose and develop a portion corresponding to the alignment key forming part except a center part of the alignment key forming part;
- and
- forming an alignment key in the center part inside the alignment key forming part and a transmission part at the circumference of the alignment key by oxidizing the substrate at the circumference of the aligment key within the aligment key forming part, wherein the transmission part is transparent after oxidizing.
