Abstract: Provided is a laser device. The laser device according to an embodiment comprises a laser source that provides a laser beam to a process object, a laser deflector that deflects the laser beam supplied from the laser source, an object lens that focuses scattered light of the laser beam that has been incident on the process object and then scattered, an image capture device that captures an image of the scattered light focused in the object lens, and a corrector that corrects a position of the laser beam by using the captured image.

Abstract: A polarizing layer includes a base film and a deformation part provided in an edge of the base film. The deformation part includes first deformation parts formed as the base film is deformed by heat, and at least one second deformation part provided between the first deformation parts adjacent to each other.

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.
