Electroluminescent display device

An electroluminescent display device comprising:

• a first electrode provided on a substrate;
• a bank disposed on the first electrode and defining first, second and third emission areas above the first electrode;
• a first emission layer in the first emission area and configured to emit light;
• a second emission layer in the second emission area and configured to emit light;
• and
• a third emission layer in the third emission area and configured to emit light,
• wherein each of the first emission layer, the second emission layer, and the third emission layer has a curved top surface,
• wherein each of the first emission area, the second emission area, and the third emission area is formed in a polygonal structure with a rounded corner, and
• wherein a third radius curvature (R3) in the rounded corner of the third emission area is larger than a first radius curvature (R1) in the rounded corner of the first emission area and a second radius curvature (R2) in the rounded corner of the second emission area.

An electroluminescent display device comprising:

• a substrate including an active area and a dummy area provided in a periphery of the active area, wherein an image is displayed in the active area, but is not displayed in the dummy area;
• and
• a bank configured to define a plurality of emission areas in the active area of the substrate, and define a plurality of dummy emission areas in the dummy area of the substrate,
• wherein the plurality of emission areas include a first emission area provided with a rounded corner, and a second emission area provided with a rounded corner, wherein an area of the second emission area is larger than an area of the first emission area, and
• wherein a second radius curvature (R2) in the rounded corner of the second emission area is larger than a first radius curvature (R1) in the rounded corner of the first emission area.
