摘要：
A manufacturing method of a display apparatus includes forming a display layer on a substrate; forming an opening by irradiating laser onto the display layer; and sealing the display layer formed on the substrate. The laser is irradiated according to a spiral movement path, and the opening is formed by irradiating the laser at least twice at the same location.
