A display device includes a display panel including a group of pixels; a control unit configured to execute deterioration monitoring for detecting a decrease in luminous efficiency of the group of pixels and first high-speed monitoring for determining whether to execute the deterioration monitoring, the first high-speed monitoring being executed at a faster speed than the deterioration monitoring; and a storage unit configured to store reference data specifying an acceptable range for executing the deterioration monitoring. The control unit executes the deterioration monitoring in a case where a first high-speed monitoring measurement value obtained by the first high-speed monitoring is within the acceptable range.

Display device

A display device includes a display panel, a temperature sensor, a characteristics measuring unit, a correction value computation unit, a correction processing unit, and a display control unit. A plurality of pixel circuits include, as an element, a light-emitting element; and a drive transistor configured to control an electric current that flows in the light-emitting element. The characteristics measuring unit obtains the measurement value when the temperature is in a predetermined temperature range and does not obtain the measurement value when the temperature is out of the temperature range.
