Abstract:
1. An organic light-emitting panel, comprising: a first pixel comprising a first, a second, and a third light-emitting cell consecutively arranged for light emission in colors different from each other and applied with ink corresponding to a first, a second, and a third luminescent color, the second light-emitting cell arranged between the first and the third light-emitting cell, each of the first, the second, and the third light-emitting cell comprising: a base layer including a first electrode; an organic light-emitting layer layered above the base layer and applied with ink including organic light-emitting material of the corresponding luminescent color; a second electrode disposed opposite the base layer with the organic light-emitting layer in between; and a plurality of banks formed above the base layer as partitions between adjacent light-emitting cells; a second pixel different from the first pixel, the second pixel comprising a first, a second, and a third light-emitting cell consecutively arranged for light emission in colors different from each other and applied with ink corresponding to a first, a second, and a third luminescent color, the second light-emitting cell arranged between the first and the third light-emitting cell, each of the first, the second, and the third light-emitting cell comprising: the base layer including a first electrode; an organic light-emitting layer layered above the base layer and applied with ink including organic light-emitting material of the corresponding luminescent color; the second electrode disposed opposite the base layer with the organic light-emitting layer in between; and a plurality of banks formed above the base layer as partitions between adjacent light-emitting cells; a non-light-emitting cell between the third light-emitting cell of the first pixel and the first light-emitting cell of the second pixel, the non-light-emitting cell not including the organic light-emitting layer and including the second electrode and a third electrode, the third electrode isolated from the first electrode and electrically connected to the second electrode; a first bank different from the plurality of banks, the first bank formed between the first pixel and the non-light-emitting cell as a partition between the third light-emitting cell of the first pixel and the non-light-emitting cell; and a second bank different from the first bank and from the plurality of banks, the second bank formed between the second pixel and the non-light-emitting cell as a partition between the first light-emitting cell of the second pixel and the non-light-emitting cell, wherein in the first bank, an inclination angle of a first wall facing the third light-emitting cell of the first pixel is larger than an inclination angle of a second wall facing the non-light-emitting cell, in the second bank, an inclination angle of a third wall facing the first light-emitting cell of the second pixel is equivalent to an inclination angle of a fourth wall facing the non-light-emitting cell, the organic light-emitting layer of the third light-emitting cell of the first pixel extends along the first wall of the first bank, and the organic light-emitting layer of the first light-emitting cell of the second pixel extends along the third wall of the second bank, and the inclination angle of each of the first wall and the second wall of the first bank and the third wall and the fourth wall of the second bank is an angle formed by a corresponding one of the first wall, the second wall, the third wall, and the fourth wall and an underlayer from which each of the first wall, the second wall, the third wall, and the fourth wall inclines.
