Light emitting display device

A light emitting display device, comprising:

• a light emitting diode that is in each of a plurality of pixel regions arranged in a display region on a substrate, and includes an emission layer forming an interface of a cardioid-shaped structure with a side surface of a bank;
• and
• an inclined reflective portion that is below the bank and disposed outside the interface,
• wherein the plurality of pixel regions includes a pixel region in which the cardioid-shaped structure is located in a first azimuth, and a pixel region in which the cardioid-shaped structure is located in a second azimuth opposite to the first azimuth, and
• wherein the reflective portion has the same cardioid-shaped structure as the interface of the corresponding pixel region.

A light emitting display device, comprising:

• an overcoat layer that is on a substrate and includes a concave groove corresponding to at least one pixel region;
• a first electrode including a reflective portion disposed along an inclined surface of the concave groove;
• a bank disposed on the first electrode and including an opening;
• and
• an organic emission layer and a second electrode disposed in the opening,
• wherein at least two of the concave groove, the reflective portion, and the opening are configured in a cardioid-shaped structure with a cusp.
