Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a display device with high display quality and high reliability.SOLUTION: An embodiment discloses a display device which includes a light source, a plurality of light guide bodies, a plurality of wiring lines, a plurality of first electrodes, a second electrode, an insulating layer and a drive unit. The light source emits light. The light guide body is extended in a first direction and guides the light. The wiring line is extended in a direction intersecting the first direction. The first electrode is connected to the wiring line, has a slit and transmits light. The second electrode is disposed between the first electrode and the light guide body and transmits light. The insulating layer is disposed between the first and second electrodes. The drive unit is connected to the wiring line and the second electrode. The drive unit varies a voltage between the first and second electrodes to generate two states: a first state in which the distance between the first and second electrodes is controlled to a first distance and the light guided in the light guide body is extracted; and a second state in which the distance between the first and second electrodes is controlled to a second distance longer than the first distance and the light is not extracted.
