Abstract

A novel functional panel that is highly convenient, useful, or reliable is provided. The functional panel includes a base material and a pair of pixels, and the base material covers the pair of pixels and has a light-transmitting property. The pair of pixels includes one pixel and another pixel, and the one pixel includes a light-emitting device and a first microlens. The light-emitting device emits light toward the base material, and the first microlens is interposed between the base material and the light emission and converges light. The first microlens includes a first surface and a second surface; the second surface is closer to the light-emitting device than the first surface is; and the second surface has a smaller radius of curvature than the first surface. The other pixel includes a photoelectric conversion device and a second microlens. The second microlens is interposed between the base material and the photoelectric conversion and converges external light incident from the base material side. The second microlens includes a third surface and a fourth surface; the third surface is closer to the photoelectric conversion device than the fourth surface is; and the fourth surface has a smaller radius of curvature than the third surface.
