Patent ID: 8223118

Claim:
An electro-optic device, comprising: a plurality of pixel electrodes arranged in a matrix, the plurality of pixel electrodes including a first pixel electrode and a second pixel electrode that is closest to the first pixel electrode, a space being formed between the first pixel electrode and the second pixel electrode; an electro-optic layer located over the first pixel electrode, second pixel electrode and the space, the electro-optic layer including a plurality of charged particles; and an opposed electrode located over the electro-optic layer and facing the first pixel electrode, the second pixel electrode and the space, wherein the plurality of charged particles includes first particles which are positively charged and second particles which are negatively charged, and wherein d/G is equal to or greater than 1/10, and is equal to or less than 3/10 when d is a distance between a first edge of the first pixel electrode and a second edge of the second pixel electrode, the first edge being closer to the second pixel electrode than any other edge of the first pixel electrode, and the second edge being closer to the first pixel electrode than any other edge of the second pixel electrode, and G is a gap formed between the opposed electrode and at least one of the first pixel electrode and the second pixel electrode.
