Patent ID: 8624275

Claim:
An organic light-emitting panel, comprising: an array of a plurality of pixels; non-light-emitting cells, each being provided between a different pair of adjacent pixels; a plurality of light-emitting cells provided in such a manner that each pixel includes at least three light-emitting cells that are arranged in an alignment and emit light of different colors, the at least 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; an underlying layer below the array of the plurality of pixels; a plurality of first electrodes, each included in the underlying layer and below a different one of the plurality of light-emitting cells; a plurality of organic light-emitting layers each in a different one of the plurality of light-emitting cells by applying, for each pixel, at least three types of ink, that contain different organic light-emitting materials corresponding one-to-one to the different colors of the light, respectively to the at least three light-emitting cells substantially at a same time; a second electrode away from the underlying layer with each organic light-emitting layer therebetween; and a plurality of banks above the underlying layer, separating the light-emitting cells, and defining each light-emitting cell, each of the plurality of pixels being structured such that: among sidewalls facing each other in two adjacent banks defining the first light-emitting cell and two adjacent banks defining the third light-emitting cell, first sidewalls adjacent to the non-light-emitting cells have larger inclination angles than second sidewalls adjacent to the second light-emitting cell, third sidewalls facing each other in two adjacent banks defining the second light-emitting cell have substantially equal inclination angles, the plurality of organic light emitting layers extend along corresponding ones of the first sidewalls, the second sidewalls, and the third sidewalls, and an inclination angle of each of the first sidewalls, the second sidewalls, and the third sidewalls is an angle formed by a corresponding one of the first sidewalls the second sidewalls, and the third sidewalls and the underlying layer from which each of the first sidewalls, the second sidewalls, and the third sidewalls inclines.
