Method for manufacturing organic light-emitting element, organic light-emitting element, organic display device, organic light-emitting device, method for forming functional layer, functional member, display device, and light-emitting device
Abstract:
A functional layer of an organic light-emitting element is formed by using an ink including a first solvent and a second solvent having equal or similar boiling points, and a functional material. The first solvent is such that an imitatively formed functional layer formed by replacing the second solvent with the first solvent, in a light-emitting region of an organic light-emitting element, is thicker at both end portions than at a central portion and top surfaces of the end portions are positioned higher than a top surface of the central portion. The second solvent is such that an imitatively formed functional layer formed by replacing the first solvent with the second solvent, in a light-emitting region of an organic light-emitting element, is thicker at a central portion than at both end portions and a top surface of the central portion is positioned higher than top surfaces of the end portions.
Abstract(Chinese):

有机发光元件的功能层通过使用包含第一溶剂和具有相同或相似沸点的第二溶剂的油墨和功能材料形成。 第一溶剂使得通过用有机发光元件的发光区域中的第一溶剂替换第二溶剂而形成的模仿功能层在两个端部处比在中心部分处更厚，并且顶表面 的端部被定位成高于中心部分的顶表面。 第二溶剂使得在有机发光元件的发光区域中通过用第二溶剂替换第一溶剂而形成的模仿功能层在中心部分比在两个端部处更厚，顶部 中心部分的表面被定位成高于端部的顶表面。
