An electrophoresis display device includes an element substrate (first substrate); a counter substrate (second substrate) arranged facing the element substrate; an electrophoresis layer arranged between the element substrate and the counter substrate and which includes a dispersion liquid which contains electrophoretic particles and a dispersion medium in which the electrophoretic particles are dispersed; a dividing wall arranged to partition the electrophoresis layer into a plurality of cells; and a sealing layer arranged between the counter substrate and the dividing wall. The sealing layer has a modulus of elasticity at 25&#xb0; C. of 1 MPa or more to 100 MPa or less.

Electrophoresis display device and electronic apparatus

The electrophoretic display device includes an element substrate (first substrate), a counter substrate (second substrate) being disposed opposite to the element substrate, a partition being disposed between the element substrate and the counter substrate, and a dispersion liquid containing electrophoretic particles and the dispersion medium, which is disposed in a cell (space) defined by the partition. Further, a pixel electrodes (first electrode) is disposed on the dispersion liquid side of the element substrate, a common electrode (second electrode) is disposed on the dispersion liquid side of the counter substrate, the electrophoretic display device includes a coating layer on a surface in contact with the dispersion liquid in at least one electrode side of the pixel electrode and the common electrode, and the contact angle to water of the coating layer is not less than 60&#xb0;.
