Abstract

A novel functional panel that is highly convenient, useful, or reliable is provided. The functional panel includes a first element, a first reflective film, and an insulating film. The first element includes a first electrode, a second electrode, and a layer containing a light-emitting material; the layer containing a light-emitting material includes a region interposed between the first electrode and the second electrode; the first electrode has a light-transmitting property; and the first electrode has a first thickness. The first electrode is interposed between a region of the first reflective film and the layer containing a light-emitting material, and the first reflective film has a second thickness. The insulating film includes a first opening portion, and the first opening portion overlaps with the first electrode. The insulating film has a first step-like cross-sectional shape, and the first step-like cross-sectional shape surrounds the first opening portion. The first step-like cross-sectional shape includes a first step, and the first step is larger than or equal to a thickness obtained by adding the second thickness to the first thickness.
