ELECTROPHORETIC PARTICLES, AND DISPLAY DEVICE AND IMAGE SHEET COMPRISING SAME

摘要

The present invention relates to electrophoretic particles, and to a display device and image sheet comprising same. The circularity of each of the electrophoretic particles for an electrophoretic display device according to one embodiment of the present invention is determined by the following FIG. 1A, wherein the circularity is no less than 0.930 and less than 1. The particle size distribution of the particles is 10% to 40%, and is determined by the following mathematical formula 2 (where A represents a projected area of a two-dimensionally projected particle, and P represents the perimeter of the two-dimensionally projected particle): [Mathematical formula 2] particle size distribution = (â/á) × 100 (where, á is an arithmetic mean diameter of particle sizes, and â is a standard deviation of the particle sizes).
