Patent ID: 7898173

Claim:
A pattern formed object comprising: a substrate on which electrodes are provided with a space between the electrodes; partition walls provided on the substrate on which the electrodes are provided and in the space between the electrodes; and a coating formed on an upper surface of the electrodes provided on the substrate in its part between the partition walls, wherein the coating comprises an EL light emitting layer formed by a dispenser method or an ink jet method, said partition walls have a liquid-nonrepellent surface and have such a sectional form that, at least in a 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, the size of the partition walls in its part provided on the electrode in a direction parallel to the substrate is not less than 1 μm, and in said 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.
