Abstract: An organic light emitting element is formed on the substrate. The organic light emitting element includes a first electrode, a bank, a surface energy, an organic light emitting member and a second electrode. The first electrode receives the first driving signal. The first electrode has a first surface energy. The bank surrounds sides of the first electrode. The surface energy lowering pattern is formed on the bank. The surface energy lowering pattern has a second surface energy that is lower than the first surface energy. The organic light emitting member is formed on the first electrode. The second electrode receives a second driving signal to display an image. Therefore, an image display quality of the display apparatus is improved.
