A novel functional panel that is highly convenient, useful, or reliable is provided. The functional panel includes a first element and a second element. The first element includes a first electrode, a second electrode, and a first optical functional layer. The first optical functional layer includes a region interposed between the first electrode and the second electrode. The first optical functional layer includes a first layer and a layer containing a first light-emitting material. The second element includes a third electrode, the second electrode, and a second optical functional layer. The second optical functional layer includes a region interposed between the third electrode and the second electrode. The second optical functional layer includes the first layer and a layer containing a photoelectric conversion material. The first layer includes a region interposed between the layer containing the first light-emitting material and the second electrode and a region interposed between the layer containing the photoelectric conversion material and the second electrode. The layer containing the photoelectric conversion material contains an organic high molecular material.
