Claim 13:
14. A method of manufacturing a window, comprising:
providing a window comprising a first non-folding portion, a second non-folding portion, and a folding portion disposed between the first and second non-folding portions; and
irradiating a laser beam to a front surface of the folding portion of the window to form a first groove in the front surface of the folding portion,
irradiating the laser beam to a rear surface of the folding portion to form a second groove in the rear surface of the folding portion, which is opposite to the front surface of the folding portion, wherein
the first non-folding portion, the second non-folding portion and the folding portion are arranged in the window in a first direction,
