Abstract: A display device having high light-extraction efficiency is provided. A low-power display device is provided. In a red or green pixel included in the display device, a light-emitting element, an optically functional layer, and a wavelength-conversion layer are stacked in this order. The light-emitting element emits blue light, the optically functional layer transmits the blue light and reflects red and green light, and the wavelength-conversion layer converts the blue light into red or green light. The blue light emitted by the light-emitting element passes through the optically functional layer and enters the wavelength-conversion layer, and red or green light is emitted to the outside. The red or green light emitted from the wavelength-conversion layer to the optically functional layer side is reflected by the optically functional layer and emitted to the outside, which improves light-extraction efficiency.

Abstract: An electronic device having a noncontact input function is provided. The electronic device includes a display device and an input device and is capable of performing an input operation even without contact. The display device includes a light-emitting device and a light-receiving device in a display portion. The input device includes a light source. The light-receiving device has a function of detecting light emitted from the light source included in the input device. Infrared light that has substantially no spectral luminous efficacy is used as the light emitted from the light source included in the input device. Therefore, even irradiation of the display portion with the light at high luminance does not affect visual recognition of the display. This structure enables a noncontact input operation with respect to the display device.
