    IPC: H01L27/15 ,  H01L33/38

    Abstract: A display device includes: a first sub-pixel having a first emission area and a first sub-area adjacent to each other in a first direction; and a bank extending around a portion of the first emission area and the first sub-area. The bank includes: a first wall extending around the first sub-area; and a second wall adjacent to the first emission area in a second direction crossing the first direction. The second wall and the first wall are spaced apart from each other in the first direction.
