Abstract
A display apparatus and method of forming the same comprise an insulating substrate; a thin film transistor formed on the insulating substrate; a first electrode electrically connected to the thin film transistor and having a first maximum roughness; a buffer layer formed on the first electrode and having a second maximum roughness lower than the first maximum roughness; an organic emission layer formed on the buffer layer; and a second electrode formed on the organic emission layer. Accordingly, it is an aspect of the present invention to provide a display apparatus and method of manufacturing the same which reduce the number of defects due to roughness of a pixel electrode.
