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: A display apparatus including first and second light-emitting elements and a light-receiving element can capture an image with high sensitivity. In the first light-emitting element, the second light-emitting element, and the light-receiving element, a first pixel electrode, a first light-emitting layer, and a common electrode; a second pixel electrode, a second light-emitting layer, and the common electrode; and a third pixel electrode, a photoelectric conversion layer, and the common electrode are stacked in this order, respectively. A first insulating layer between the second light-emitting element and the light-receiving element and a second insulating layer between the first light-emitting element and the second light-emitting element each contain a positive photosensitive material having a high visible-light-transmitting property. A transmittance of light having a wavelength that is at least part of a visible light wavelength in the first insulating layer is lower than that in the second insulating layer.

Abstract: A high-resolution, high-definition, or large display apparatus is provided. A metal mask is placed over an EL layer and film deposition is performed with the metal mask, whereby an island-shaped counter electrode is formed. Then, the EL layer is processed using the counter electrode as a hard mask. Alternatively, after an EL layer and a counter electrode are formed over an entire surface, processing using a metal mask is performed. An insulating layer that electrically insulates adjacent pixel electrodes from each other is positioned between adjacent light-emitting devices. A resist mask is formed over the insulating layer. A plurality of EL layers and a plurality of counter electrodes overlapping each other over the insulating layer are partly removed using the resist mask, whereby part of the insulating layer is exposed. Thus, the adjacent light-emitting devices are electrically insulated from each other over the insulating layer.
