Patent ID: 8901546

Claim:
An organic light-emitting panel comprising: an array of a plurality of pixels; a plurality of light-emitting cells provided in such a manner that each pixel includes three light-emitting cells that are arranged in an alignment and emit light of different colors, the three light-emitting cells including a first light-emitting cell located at an end of the alignment, a second light-emitting cell located at a central portion of the alignment, and a third light-emitting cell located at another end of the alignment, each light-emitting cell including an underlying layer, a first electrode provided in the underlying layer, an organic light-emitting layer, and a second electrode formed on an opposite side of the organic light-emitting layer from the underlying layer, each organic light-emitting layer being formed by applying, for each pixel, three types of ink respectively to the three light-emitting cells in an order of the first light-emitting cell, the second light-emitting cell and the third light-emitting cell, the three types of ink containing different organic light-emitting materials corresponding one-to-one to the different colors of light; and a plurality of banks which, formed above the underlying layer, define each light-emitting cell by separating the light-emitting cells one from another, the plurality of pixels including a pixel that is structured such that two inner sidewalls, which face each other in two adjacent banks defining the first light-emitting cell, have equal inclination angles, and among two inner sidewalls facing each other in two adjacent banks defining the second light-emitting cell, a sidewall of a bank located on a side of the third light-emitting cell has a larger inclination angle than a sidewall of a bank located on a side of the first light-emitting cell, wherein the organic light-emitting layer has a uniform film thickness across the organic-light emitting panel.
