Electrophoresis display device and electronic apparatus
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° C. of 1 MPa or more to 100 MPa or less.
