Abstract: A display substrate includes a base substrate, a switching device on the base substrate and an alignment pattern. The switching device includes an active pattern, a gate insulation layer pattern partially covering the active pattern, a gate electrode on the gate insulation layer pattern, and a source electrode and a drain electrode electrically connected to the active pattern. The alignment pattern has a multi-layered structure and is spaced apart from the switching device on the base substrate. The alignment pattern includes materials which have different transmittances.

Abstract: A method of manufacturing a polysilicon (poly-Si) layer, a method of manufacturing an organic light-emitting display apparatus using the method, and an organic light-emitting display apparatus manufactured by using the method. The method includes forming an amorphous silicon (a-Si) layer on a substrate having first and second areas, thermally treating the a-Si layer to partially crystallize the a-Si layer into a partially crystallized Si layer, removing a thermal oxide layer through a thermal treatment, selectively irradiating the first areas with laser beams to crystallize the partially crystallized Si layer.
