Abstract:
A display device includes a substrate that is provided on a display face side, an opposed substrate that is provided opposing the substrate, a display layer that is provided between the substrate and the opposed substrate and is filled with a dispersion liquid in which white particles and black particles are dispersed in a dispersion medium, and a particle constrained layer that is provided in the display layer to allow the particles to move in a thickness direction of the display layer and to prevent the particles from moving in an in-plane direction of the display layer. A void ratio of the particle constrained layer of the substrate side is higher than that of the opposed substrate side.
