Abstract
A method for manufacturing a display device includes the steps of: placing a member having a first alignment mark and a second alignment mark spaced apart from the first alignment mark on a stage; adsorbing the member onto the upper surface of the stage; capturing an image of the member with a camera placed on the stage; comparing the captured phase of the second alignment mark with a first preset phase of the second alignment mark; adsorbing the member to a bending part placed spaced apart from the stage; and bending the member to the bending part.
