PROBLEM TO BE SOLVED: To provide an interference filter having a wide transmission range and a display device including the interference filter.SOLUTION: The display device includes an interference filter and a display layer facing the interference filter. The interference filter includes a first common layer having a first region and a second region, a second common layer facing the first common layer, a first spacer layer which is provided between the first common layer and the second common layer and has a first portion facing the first region and a second portion facing the second region and having a thickness different from that of the first portion, a second spacer layer which faces at least one of the first portion and the second portion of the first spacer layer via the second common layer and is formed of the same material as the first spacer layer, and a coating layer facing the second common layer via the second spacer layer. The first common layer, the first spacer layer, the second common layer, the second spacer layer, and the coating layer are formed of dielectric films. |
