Display device and manufacturing method of window

A display device comprising:

• a display module;
• and
• a window which is disposed on the display module and in which a first non-folding region, a folding region, and a second non-folding region are sequentially defined in a first direction, wherein
• the window includes:
• a base layer;
• and
• a lower hard coating layer disposed between the base layer and the display module, and
• the lower hard coating layer includes:
• a first portion overlapping the first non-folding region and the second non-folding region of the window;
• and
• a second portion overlapping the folding region of the window, the second portion including a highly-stretchable polymer material selected from the group consisting of polyurea, polyurethane, and polyester.

A method for manufacturing a window, the method comprising:

• preparing a base layer in which a first region, a second region, and a third region are sequentially defined in a first direction;
• forming a first hard coating layer by applying a first hard coating material onto an upper surface of the base layer;
• and
• forming a second hard coating layer on a lower surface of the base layer,
• wherein the forming of the second hard coating layer includes:
• applying the first hard coating material onto the first region and the third region of the base layer to form a first portion;
• and
• applying a second hard coating material including a highly-stretchable polymer material onto the second region of the base layer to form a second portion.
