Light-emitting display device and method of manufacturing the same

A method of manufacturing a light-emitting display device, the method comprising:

• forming a plurality of subpixels on a substrate;
• forming a first electrode in each of the subpixels;
• forming a bank to define an emission part in each of the subpixels, wherein the bank has an upper surface that has a larger degree of surface roughness than an upper surface of the first electrode;
• forming a first common layer over the subpixels to cover the first electrode and the bank;
• forming a light-emitting layer on the first common layer to correspond to the emission part of each of the subpixels;
• forming a second common layer on the light-emitting layer over the subpixels;
• and
• forming a second electrode on the second common layer.

A light-emitting display device comprising:

• a plurality of subpixels disposed on a substrate;
• a first electrode at each subpixel;
• a bank overlying an edge of the first electrode;
• a roughness-inducing layer under the bank between the first electrode of one of the subpixels and the first electrode of an adjacent subpixel;
• an emission part of the subpixels defined by the bank;
• a light-emitting layer corresponding to the emission part of the subpixels;
• and
• a second electrode on the light-emitting layer over the plurality of subpixels.
