ABSTRACT:
A display apparatus includes a light-emitting unit. The light-emitting unit includes a first electrode, a bank, an organic light-emitting layer and a second electrode. The first electrode is formed on a substrate. The first electrode receives a first driving signal from a circuit unit. The bank surrounds sides of the first electrode and has a receiving portion formed on an upper face of the bank. The organic light-emitting layer is formed on the first electrode. The second electrode is formed on the organic light-emitting layer. The second electrode receives a second driving signal from the circuit unit. Therefore, even though the organic light-emitting material is abnormally dropped onto an unintended position, the receiving portion prevents the organic light-emitting material from flowing into a neighboring cavity, so that yield increases and productivity is enhanced.
