摘要： A method of manufacturing a display apparatus includes forming a first substrate on a support substrate; forming a first barrier layer on the first substrate; and forming a conductive layer by implanting n-type impurities or p-type impurities in the first barrier layer and at least a portion of the first substrate. A display apparatus includes a conductive layer arranged on a substrate and a barrier layer arranged on the conductive layer. The conductive layer is doped with n-type impurities when the first barrier layer is doped with n-type impurities, and the conductive layer is doped with p-type impurities when the first barrier layer is doped with p-type impurities.

摘要： Provided are a laser annealing apparatus and a method of manufacturing a substrate having a poly-Si layer using the laser annealing apparatus. The laser annealing apparatus includes a laser beam source that emits a linearly polarized laser beam, a polygon mirror that rotates around a rotation axis and reflects the laser beam emitted from the laser beam source, a first Kerr cell disposed on a laser beam path between the laser beam source and the polygon mirror, and a first optical element that directs the laser beam reflected by the polygon mirror toward an amorphous Si layer where the laser beam is irradiated upon the amorphous Si layer.
