Abstract: An apparatus for manufacturing a display device includes: a light source for generating a first beam; a beam converter including an axicon lens for converting the first beam into a second beam and a relay lens for converting the second beam into a third beam; a scanner including a first mirror for reflecting the third beam in a first direction and a second mirror for reflecting the third beam in a second direction different from the first direction; and a scan lens having an effective focal length and being for converting the third beam output from the scanner into a fourth beam. The scan lens including first through fifth lens respectively having first through fifth focal lengths and a cover window. An absolute value of the first focal length is smaller than an absolute value of each of the second through fifth focal lengths.
