Display device for controlling an organic light emitting layer thickness

摘要

A display device includes an array of light emitting cells. Banks define each of the light emitting cells. The light emitting cells include 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. First and third banks border the first light emitting cell with the first bank being closer to a periphery of the array than the second bank. Second and fourth banks border 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 an innermost sidewall of the third bank that is adjacent the second light emitting cell is different than an inclination angle of an innermost sidewall of the first bank that is adjacent the first light emitting cell.
