Display device configured to supply a driving current in accordance with a signal voltage selected based on a temperature dependency of the driving current and driving method thereof

摘要

In a display device including a driving transistor a driving current flows in accordance with a signal voltage supplied via a data line, so that gray scale display in accordance with the signal voltage is carried out. An electro-optical element emits light in response to the driving current. The driving transistor is provided with a signal voltage at displaying a center gray scale among all display gray scale levels within a voltage region in which the driving current in a temperature range of 0° C. to 40° C. is in a range of 98% to 102% of a driving current that flows at an average driving temperature.
