    Abstract: A high-resolution display device is provided. The display device includes a plurality of light-emitting units emitting light of different colors. The light-emitting unit has a microcavity structure and intensifies light with a specific wavelength. In the light-emitting units emitting light of different colors, reflective layers with different thicknesses are formed, an insulating layer is formed to cover the reflective layers, and then a top surface of the insulating layer is subjected to planarization treatment, whereby an insulating layer with different thicknesses is formed. After that, light-emitting elements emitting white light are formed over the planarized top surface of the insulating layer to overlap with the respective reflective layers, whereby the light-emitting units that intensify different colors due to different optical path lengths are separately formed.

    Abstract: A display panel or a display device with high display quality is provided. The display panel includes a light-emitting element, an insulating layer, a protective layer, and a conductive layer. The light-emitting element includes a first electrode, a light-emitting layer, and a second electrode. The light-emitting element emits light to the protective layer side. The insulating layer includes a first opening overlapping with the first electrode. The insulating layer covers an end portion of the first electrode. The light-emitting layer overlaps with the first electrode through the first opening. The second electrode is positioned over the light-emitting layer. The protective layer is over and in contact with the second electrode. The protective layer functions as a protective layer of the light-emitting element. The protective layer includes a second opening overlapping with the insulating layer. The conductive layer is connected to the second electrode through the second opening. The conductive layer functions as an auxiliary wiring of the second electrode.

    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.
