有机EL元件的制造方法、有机EL装置和电子设备
摘要：
本发明利用涂布法与含有低分子材料的油墨的组合，形成得到均匀发光的有机EL元件。有机EL元件的制造方法的特征在于，具有在由像素电极和包围像素电极的周围的隔壁构成的涂布区域涂布含有功能层形成材料的油墨的工序，该工序包括以将油墨与隔壁的侧面的接触角设为θbc、将油墨与涂布有油墨的涂布区域的表面的接触角设为θlc时，满足下述式(1)～(3)的下方式涂布上述油墨的工：θbc≤θlc…(1)；θbc≤5度…(2)；θlc≤20度…(3)。
摘要（英）：

An organic EL element having uniform light emission can be formed by using a coating method and ink containing low-molecule material. The organic EL element manufacturing method includes coating ink which contains a functional layer forming material in a coating region which is configured by a pixel electrode and a partition wall which surrounds a periphery of the pixel electrode, where, in the coating ink, the ink is coated so as to satisfy the following expressions (1) to (3) in a case where a contact angle of the ink with respect to the side surface of the partition wall is set to [theta]bc and a contact angle with respect to a surface of the coating region where the ink is coated is set to [theta]lc: [theta]bc<=[theta]lc (1) [theta]bc<=5 DEG (2) [theta]lc<=20 DEG (3).
