ELECTRONIC PAPER DISPLAY DEVICE AND MANUFACTURING METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electronic paper display device with a structure in which rotation balls with different sizes are provided on the same plane and the rotation characteristics of the rotation balls are kept uniform, and a manufacturing method for the electronic paper display device.

SOLUTION: An electronic paper display device comprises: rotation balls 120 including a first rotation ball 120a and a second rotation ball 120b smaller than the first rotation ball 120a; a partition wall structure 110 including a cavity 112 in which the rotation ball 120 is disposed and partitioning the rotation ball 120 in a lateral direction; an electrode structure 130 provided for the partition structure 110 and supplying driving voltage to the rotation ball 120; and a space adjuster 152 provided in the cavity 112 to face the rotation ball 120 in a direction vertical to the lateral direction.
