Abstract: An electronic device capable of operation of a three-dimensional movement is provided. An electronic device capable of performing various types of actuation by simple operation is provided. A display device includes a control portion, a display portion, and a detection portion. The display portion includes a screen displaying an image, and the detection portion has a function of obtaining positional information of a detection target that is in contact with the screen or approaches above the screen and outputting the information to the control portion. The control portion has a function of executing first processing based on first operation, a function of executing second processing when second operation is successively performed after the first operation, and a function of executing third processing when third operation is successively performed after the second operation. The first operation is operation in which two pointed positions are detected on the screen, the second operation is operation in which the two pointed positions move to reduce the distance therebetween, and the third operation is operation in which the two pointed positions move in the normal direction with respect to the screen from the state where they are in contact with the screen.

Abstract: A display device that enables a user to see a bright image is provided. In the display device, a first substrate, a light-emitting element, an insulating layer, a coloring layer, a planarization layer, a plano-convex lens, a resin layer, and a second substrate are stacked in this order from the bottom. The plano-convex lens is curved outwards in the upper direction of the display device. A convex portion of the plano-convex lens is in contact with a resin layer, and the refractive index of the resin layer is lower than the refractive index of the plano-convex lens. Light emitted by the light-emitting element is converged in the forward direction by the plano-convex lens.

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.
