Organic EL panel and method for manufacturing same

摘要

An organic EL panel including an organic light-emitting layer with a miniaturized structure formed by a wet process, allowing for excellent light-emitting characteristics, and a method for manufacturing the same. Specifically, the display panel includes: a substrate; first electrodes arranged above the substrate along a first and second direction intersecting with each other; a first, second, and third organic light-emitting layer arranged above the first electrodes so as to be adjacent to each other in the second direction, and each containing an organic light-emitting material corresponding to a different emission color; a first bank separating the first and the second layer; a second bank separating the second and the third layer; and a second electrode disposed above the first, the second, and the third layer and being different in polarity from the first electrodes. The first and the second bank are different in width along the second direction.

1. An organic EL panel, comprising:
a substrate; an array of first electrodes, the first electrodes being arranged above the substrate along a first direction and a second direction intersecting with each other, and the array being composed of rows each extending along the first direction; a first organic light-emitting layer, a second organic light-emitting layer, and a third organic light-emitting layer arranged above the array of first electrodes so as to be parallel to each other along the first direction, and each containing an organic light-emitting material corresponding to a different emission color; a pair of first banks formed along the first direction at either side of the first organic light-emitting layer; a second bank formed between the second organic light-emitting layer and the third organic light-emitting layer; and a second electrode disposed above the first organic light-emitting layer, the second organic light-emitting layer, and the third organic light-emitting layer, and being different in polarity from the array of first electrodes, wherein each of the pair of first banks is the same in width along the second direction, and is greater in width along the second direction than the second bank, and the first organic light-emitting layer, the second organic light-emitting layer, and the third organic light-emitting layer are the same in width along the second direction.
