Display device and its driving and manufacturing methods

摘要

At least two regions having different colors and electrical characteristics are defined in a rotatable particle. The rotatable particle receives a rotation moment from an external electric field reaction. A base holds rotatably each rotatable particle. An electric field generating unit generates only during a certain electric field generating period an electric field in a spatial area where the rotatable particle is disposed. The intensity of the electric field is monotonously lowered during at least one third of the certain electric field generating period on a backward side of the period. It is possible to reduce a variation in a rotation operation and display a high quality image.
