PROBLEM TO BE SOLVED: To provide a display device reducing drive voltage and a driving method thereof.SOLUTION: A display device contains a light emission unit emitting light, plural light guide units, plural light extraction units and a control unit. The light guide unit leads light. The light extraction unit has a first electrode and a second electrode and faces the light guide unit. The light extraction part forms a first state and a second state in which a light extraction amount is different by the light extraction part and the light guide unit being contact or non-contact depending on electric potential difference between the first and second electrodes. The control unit is connected to the first and second electrodes, and sets the second electrode to a first potential in a first period and sets the second electrode to a second potential which is lower than the first potential in a second period. In the first period, the first electrode is set to the second potential in the first state and set to the first potential in the second state. In the second period, the first electrode is set to the first potential in the first state and set to the second potential in the second state. |
