Display device and electronic device including the same

An electronic device, comprising:

• a display panel including a pixel including a driving transistor, a compensation transistor connected to a gate electrode of the driving transistor and a first electrode of the driving transistor, an initialization transistor connected to a first electrode of the compensation transistor, and a light-emitting element configured to emit a light based on an initialization voltage applied through the compensation transistor and the initialization transistor and a low power supply voltage;
• an initialization voltage generator configured to generate the initialization voltage;
• a current sensor configured to sense a sensing current flowing through the compensation transistor and the initialization transistor to generate sensing data;
