To provide: a substrate for display device, in which generation of an area not filled with liquid material and mixing (color mixing) between liquid materials are suppressed when a functional film is formed by a method using liquid material, such as the IJ method, and display quality in display device is improved; a manufacturing method thereof; and a color filter substrate, a thin film transistor array substrate, a liquid crystal display device and an organic electroluminescent display device each comprising the substrate for display device. A substrate for display device having a structure with a functional film partitioned by a bank on the substrate, the functional film being represented by a contour pattern extending to a corner inside a bank.
