Abstract
In a display device, a first electrode and a second electrode are mounted on a first substrate, a second substrate is arranged to face the first substrate with a gap provided between the first substrate and the second substrate, and a third electrode is mounted on the second substrate. A first layer is formed in a gap between the first substrate and the second substrate at the side of the first substrate and containing a ECL material that emits light due to electrochemical oxidation or reduction. A second layer is formed in the gap between the first substrate and the second substrate at the side of the second substrate and containing a EC material having the color changed due to electrochemical oxidation or reduction.
