Abstract
A display device includes: a substrate provided on a side of the display surface; a counter substrate disposed to face the substrate; a display layer provided between the substrate and the counter substrate and filled with a dispersion liquid formed of a dispersion medium in which white particles and black particles charged with polarities opposite to each other are dispersed; and a particle constrained layer provided in the display layer, and suppresses the white particles and the black particles from moving in an in-plane direction of the display layer, while allowing the particles to move in the thickness direction of the display layer. In the display device, a particle constrained layer is provided to be separated from the substrate.

A display sheet comprising:
- a first substrate which is provided on a side of a display surface;
- a second substrate which is disposed to face the first substrate;
- a display layer which is provided between the first substrate and the second substrate and filled with a dispersion liquid in which at least one kind of particle is dispersed in a dispersion medium, the particles being charged positively or negatively;
- and
- a particle constrained layer which is provided in the display layer,
- wherein the particle constrained layer is provided to be separated from the first substrate;
- and
- a separated distance between the particle constrained layer and the first substrate is equal to or more than one time and equal to or less than five times an average particle diameter of the particles.
