Abstract: A display device including a plurality of pixels disposed on a substrate, each pixel including a plurality of sub-pixels; a first electrode disposed in each sub-pixel and connected to transistors for driving the plurality of sub-pixels to emit light; and a bank including a plurality of bank holes, each bank hole exposing a portion of the first electrode and defining emission light-areas of the sub-pixels. Further, each sub-pixel includes a sub-pixel pattern disposed on a bottom surface of the bank hole and contacting exposed surfaces of the first electrode, and extending continuously on sidewalls of the bank hole and along top outside edge surfaces of the bank. Also, a thickness of the sub-pixel pattern decreases step-by-step as the sub-pixel pattern extends along the top outside edge surfaces of the bank in a direction toward an adjacent sub-pixel.
