Patent ID: 8546820

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