| 发明名称 | Optical filter including ring-shaped electrode having a slit | ||
| 摘要 | An optical filter includes: a first substrate; a second substrate opposed to the first substrate; a first reflecting film provided to the first substrate; a second reflecting film provided to the second substrate and opposed to the first reflecting film; a first electrode provided to the first substrate in a peripheral area of the first reflecting film; a second electrode provided to the first substrate in a peripheral area of the first electrode; a third electrode provided to the second substrate and opposed to the first electrode; and a fourth electrode provided to the second substrate and opposed to the second electrode. | ||

| 主权项 | 1. An optical filter comprising: a first substrate; a second substrate opposed to the first substrate; a first reflecting film provided to the first substrate; a second reflecting film provided to the second substrate and opposed to the first reflecting film; a first electrode provided to the first substrate in a peripheral area of the first reflecting film in a plan view; a second electrode provided to the first substrate in a peripheral area of the first electrode in the plan view; a third electrode provided to the second substrate and opposed to the first electrode; a fourth electrode provided to the second substrate and opposed to the second electrode; a first wire connected to the first electrode; and a second wire connected to the second electrode, wherein the first electrode has a first ring-like shape, the second electrode has a second ring-like shape having a first slit, and a part of the first wire is formed in an area where the first slit is formed. | ||
