    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.

    Abstract: To provide a display device with excellent display quality, in a display device including a signal line, a scan line, a transistor, a pixel electrode, and a common electrode in a pixel, the common electrode is included in which an extending direction of a region overlapping with the signal line differs from an extending direction of a region overlapping with the pixel electrode in a planar shape and the extending directions intersect with each other between the signal line and the pixel electrode. Thus, a change in transmittance of the pixel can be suppressed; accordingly, flickers can be reduced.

    Abstract: To provide a display device with a novel structure that can achieve both thickness reduction and favorable display quality. In a structure of a display device including a liquid crystal layer between a pixel electrode and a counter electrode, a common electrode and an electrode of a capacitor in a touch sensor on the counter electrode side are formed integrally and supplied with a pulse signal. On the element substrate side, a signal to be supplied to a capacitor line that forms a capacitance with the pixel electrode is in conjunction with the pulse signal so as to cancel a change in an electric field applied to the liquid crystal layer. Such a structure can achieve a display device with a touch sensor function that can cancel a change in an electric field applied to a liquid crystal layer even when the electric field is changed by a pulse signal.

    Abstract: [Object]Provided is a novel display device without deterioration of display quality or a novel display device in which flickering due to a reduced refresh rate is suppressed.[Solution]The display device includes a pixel for displaying a still image at a frame frequency of less than or equal to 1 Hz. The pixel includes a liquid crystal layer. The liquid crystal layer has a dielectric constant anisotropy of higher than or equal to 2 and lower than or equal to 3.8.
