摘要:
A method of manufacturing a display apparatus includes: forming a peripheral circuit, a first electrode and a bank on a substrate; forming a surface energy lowering pattern on the bank; forming an organic light emitting member on the first electrode; and forming a second electrode on the organic light emitting member. The first electrode receives a first driving signal. The first electrode has a first surface energy. The bank surrounds at least one side of the first electrode. The surface energy lowering pattern has a second surface energy which is lower than the first surface energy. The second electrode receives a second driving signal to display an image. Therefore, an image display quality of the display apparatus is improved.
