Abstract: A light-emitting display device can include a plurality of first electrodes over a substrate; a bank to overlap an area between the first electrodes and an edge of each of the first electrodes; a bank recess in the bank at the area between the first electrodes; a hard mask pattern to partially overlap the bank recess and to abut an upper part of the bank; an organic layer on the first electrodes and the bank, the organic layer being discontinuous between an upper part of the hard mask layer pattern and the bank recess; and a second electrode. Also, the bank can include a bank lower portion having a first height under the bank recess, a bank body portion around the bank recess, the bank body portion having an acute taper with respect to the substrate, and a bank overlap portion to overlap the plurality of first electrodes.
