1. A method of manufacturing a display apparatus comprising:
forming a thin film transistor in a panel area on a base substrate including the panel area and a margin area disposed next to the panel area;
forming a conductive layer on the base substrate on which the thin film transistor is formed;
patterning the conductive layer to form a dummy pattern in the margin area and a pixel electrode electrically connected to the thin film transistor in the panel area;
forming a light emitting layer and an opposite electrode on the pixel electrode; and
cutting the margin area of the base substrate to separate the margin area from the panel area.
