A light-emitting display device comprising:
- a plurality of first electrodes spaced apart from each other 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 provided in the bank at the area between two adjacent first electrodes among the plurality of first electrodes;
- a hard mask pattern comprising a first part positioned at an upper part of the bank surrounding the bank recess and a second part horizontally extended from the first part to partially overlap the bank recess;
- an organic layer over the first electrodes and the bank, the organic layer being discontinuous between the upper part of the bank and the bank recess;
- and
- a second electrode over the organic layer,
- wherein a first portion of the hard mask pattern and a second portion of the hard mask pattern are disposed on opposite sides of the bank recess.
