Method for manufacturing a display device

A method for manufacturing a display device, the method comprising:

• providing a first display device assembly including a display module, a first window adhesive layer disposed on the display module, a first window disposed on the first window adhesive layer, and a first protective layer disposed on the first window;
• removing the first protective layer;
• removing the first window by providing an acid solution on the first display device assembly;
• providing a second window that is disposed on the display module after the first window has been removed;
• and
• forming a second display device assembly by providing a second protective layer on the second window,
• wherein a ratio of a first adhesive strength of the first window adhesive layer to the first window to a second adhesive strength of the first window adhesive layer to the second window is in a range of about 1:1 to about 1:0.9.

A method for manufacturing a display device, the method comprising:

• providing a first display device assembly comprising a display module, a first window disposed on the display module, and a plurality of first layers disposed between the first window and the display module, the plurality of first layers including at least one of a first optical adhesive layer, a first optical layer, and a first window adhesive layer;
• removing the first window by providing an acid solution on the first display device assembly;
• providing a second window that is disposed on the display module after the first window is removed to provide a second display device assembly,
• wherein the second display device assembly includes at least one of the plurality of first layers included in the first display device assembly.
