Abstract:
1. A method of manufacturing a display apparatus, the method comprising: preparing a mother substrate in which at least first, second and third display regions are sequentially arranged in a first direction, wherein amorphous semiconductor layers are formed in each of the display regions; disposing the mother substrate on a stage that moves in the first direction and in a second direction substantially perpendicular to the first direction; forming an active layer by moving the stage in the second direction, irradiating a first laser beam having a width greater than or substantially identical to the width of a side of the first display region in the first direction from a first laser irradiation unit disposed on an upper portion of the mother substrate, irradiating a second laser beam having a width greater than or substantially identical to the width of a side of the third display region in the first direction from a second laser irradiation unit disposed on the upper portion of the mother substrate, and crystallizing the amorphous semiconductor layers of the first display region and the third display region; and forming the display apparatus on an upper portion of the active layer.
