Abstract: When a current-driven display device with an internal compensation method operates in a pause driving mode, a non-light emission period according to a light emission duty is provided in both a refresh frame period and a non-refresh frame period, and an on-bias applying period for applying on-bias to a drive transistor in a pixel circuit is provided in both the non-light emission periods. In the non-light emission period in the refresh frame period, an on-bias applying period is provided in a period from when data writing with threshold compensation is performed to when the light emission period starts. Thus, even when the light emission duty is low, the difference in the stress state of the drive transistor between the refresh frame period and the non-refresh frame period is reduced.
