ABSTRACT:
The invention provides a method for suppressing insufficient spread of droplets or mixing of the droplets in neighboring regions when a liquid material is disposed in the regions on a substrate by ejecting the droplets composed of the liquid material. In addition, for a display device, the structure in which insufficient spread of droplets or mixing of the droplets in neighboring regions can be suppressed and the manufacturing method therefor are provided. To accomplish the above, substantially square regions can be formed by a partition provided on a substrate. In each region, among internal surfaces and of the partition surrounding this region, the internal surfaces forming the long sides of the region have irregularities. In addition, the distance between parts of the partition opposing each other with one of regions provided therebetween is increased and decreased along the long side of the region. Furthermore, along the long side of the region, the width of the partition will be increased and decreased.
