US Patent 7898173 Pattern formed object for an electroluminescent display

A pattern formed object for an electroluminescent element includes a substrate; partition walls provided on the substrate; and a coating stacked on the substrate in its part between the partition walls. The partition walls have a sloped liquid-nonrepellent surface and have such a sectional form that, at least in the lower part of the partition wall, as the distance from the substrate increases, the size of the partition wall in a direction parallel to the substrate decreases, and, in the coating, the ratio of the maximum thickness (Tmax) to the minimum thickness (Tmin), Tmax/Tmin, is not more than 130% as measured in the coating in its part between the lower ends of the partition walls adjacent to each other.
