Abstract
The present invention is directed to an electrophoretic display film comprising: a) microcups each having a first shape, and b) remaining microcups which take up at least 10% of the total number of microcups and have shapes different from the first shape. The microcup designs of the present invention not only may reduce the Moiré pattern, but it may also make the defects of the microcup walls much less noticeable, and therefore increase the cutting yield.
