Abstract

本发明提供一种具有作为晶体管元件的有机薄膜晶体管的有机薄膜晶体管基板的制造方法,以提供可用更少工序形成堤坝的制造方法为目的。根据本发明的有机薄膜晶体管基板的制造方法,其中该有机薄膜晶体管基板在基板上的第1区域形成有机薄膜晶体管,具有与第1区域邻接并用于形成发光元件的第2区域,在第2区域的周边部形成了堤坝部,该制造方法包括:第1工序,在基板上的第1区域形成有机薄膜晶体管,同时一直到第2区域都形成此有机薄膜晶体管所具有的栅绝缘层及有机半导体层中的至少一层,在第2区域上形成由形成在该区域上的叠层结构构成的堤坝前驱体层;以及第2工序,去除堤坝前驱体层中的周边部以外的区域,形成由残存的堤坝前驱体层构成的堤坝部。
Provided is a method for producing an organic thin film transistor substrate having an organic thin film transistor as a transistor element. The method can provide a manufacturing method which can form a bank with a reduced number of steps. The organic thin film transistor substrate has a first region where an organic thin film transistor is formed, a second region adjacent to the first region for forming a light emission element, and a bank portion formed at the periphery of the second region. An organic thin film transistor is formed on the first region on the substrate. The method includes: a first step for forming an organic thin film transistor, forming at least one of a gate insulating layer and an organic semiconductor layer of the organic thin film transistor so as to reach the second region, and forming a bank precursor layer having a layered structure formed on the second region; and a second step for removing a region excluding the peripheral portion of the bank precursor layer so as to form a bank portion by the remaining bank precursor layer.
