Abstract
A display device may include a light-emitting element and a controllable element. The light-emitting element may emit a light. The controllable element may neighbor the light-emitting element in a plan view of the display device and may include a fluid set. The fluid set may include at least one of a light-reflecting element set and a black element set. The controllable element may have a first average reflectance value in a first direction if the controllable element receives no voltage or receives a first voltage. The controllable element may have a second average reflectance value in the first direction if the controllable element receives a second voltage. The second voltage may be unequal to the first voltage. The second average reflectance value may be unequal to the first average reflectance value.
