Abstract: A display device includes pixels each including a first sub-pixel, a second sub-pixel and a third sub-pixel. Each of the pixels includes a bank disposed on a substrate, wherein the bank includes a first opening defining a light-emitting area of the first sub-pixel, a second opening defining a light-emitting area of the second sub-pixel, and a third opening defining a light-emitting area of the third sub-pixel, and a spacer being disposed on the bank and surrounding the third opening. Spacers in adjacent pixels have different shapes from each other.
