Patent ID: 8546821

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 that is located in a central region of the array and a second light emitting cell that is located in a peripheral region of the array, the plurality of banks includes a first bank, a second bank, a third bank, and a fourth bank, the first bank and the second bank each bordering the first light emitting cell with the first bank being closer to a periphery of the array than the second bank, the third bank and the fourth bank each bordering the second light emitting cell with the third bank being closer to the periphery of the array than the fourth bank, an inclination angle of a first sidewall of the third bank that is adjacent the second light emitting cell is different than an inclination angle of a second sidewall of the first bank that is adjacent the first light emitting cell, the organic light emitting layer of the first light emitting cell extends along the second sidewall of the first bank and the organic light emitting layer of the second light emitting cell extends along the first sidewall of the third bank, and the inclination angle of each of the first sidewall of the third bank and the second sidewall of the first bank is an angle formed by a corresponding one of the first sidewall of the third bank and the second sidewall of the first bank and an underlayer from which each of the first sidewall and the second sidewall inclines.
