Abstract: A method of manufacturing a display apparatus includes forming a first conductive layer on a base substrate including a panel area and a margin area disposed next to the panel area, the margin area including a dummy pattern area, forming a photoresist layer on the first conductive layer, forming a photoresist pattern by exposing and developing the photoresist layer, forming a first conductive pattern by etching the first conductive layer using the photoresist pattern, and removing the photoresist pattern. The forming the first conductive pattern includes forming a first pixel circuit pattern in the panel area, and forming a dummy pattern in the dummy pattern area of the margin area. An opening ratio of a portion where the dummy pattern is not formed with respect to the dummy pattern area is about 30% or more.
