Abstract
A display apparatus is provided. The display apparatus includes a substrate having a display area and a pad area, an active layer in the display area of the substrate, a pad electrode in the pad area of the substrate, and a planarization layer on the active layer and the pad electrode with a contact hole for exposing a part of the active layer. A maximum diameter of the contact hole has a size considering an increase in maximum diameter of the contact hole while the planarization layer in the pad area is removed after the planarization layer is formed on the display area and the pad area. Accordingly, it is possible to minimize an increase in size of the contact hole in the display area while the planarization layer is removed, thereby reducing process defects, such as a gap error, of the display apparatus.
