Patent ID: 8536589

Claim:
A display device, comprising: an array of a plurality of light emitting cells, each of the plurality of light emitting cells including a first electrode, a second electrode, and an organic light emitting layer located between the first electrode and the second electrode; and a plurality of banks above the first electrode that partition the organic light emitting layer to define each of the plurality of light emitting cells, wherein the plurality of light emitting cells includes a first light emitting cell and a second light emitting cell that are adjacent to one another and located in a peripheral region of the array, the first light emitting cell being closer to a center of the array than the second light emitting cell, the plurality of banks includes a first bank that borders the first light emitting cell and the second light emitting cell, an inclination angle of a first sidewall of the first bank that is adjacent the first light emitting cell is greater than an inclination angle of a second sidewall of the first bank that is adjacent the second light emitting cell, the organic light emitting layer of the first light emitting cell extends along the first sidewall of the first bank and the organic light emitting layer of the second light emitting cell extends along the second sidewall of the first bank, and the inclination angle of each of the first sidewall and the second sidewall of the first bank is an angle formed by a corresponding one of the first sidewall and the second sidewall of the first bank and an underlayer from which each of the first sidewall and the second sidewall inclines.
