Abstract
A display device includes: a plurality of first colored particles contained in a space between a first substrate and a second substrate; a light-emitting portion having a first light-emitting element provided on the first substrate, and a first-light-emitting-element driving circuit provided on the first substrate and configured to drive the first light-emitting element; a first transparent portion disposed in a direction along a main surface of the first substrate with respect to the light-emitting portion; a first electrode provided in the light-emitting portion; and a second electrode provided in the first transparent portion and being nckudestransparent. The display device is capable of switching between a light-transmitting state of the first transparent portion in which the first electrode attracts the plurality of first colored particles, and a light-blocking state of the first transparent portion in which the second electrode attracts the plurality of first colored particles.
