Abstract
A display unit with a high definition is provided. The display unit includes a transistor, a light-emitting diode, a first conductive layer, a second conductive layer, a first insulating layer, and a second insulating layer. The transistor is electrically connected to the first conductive layer, and the first conductive layer and the first insulating layer are positioned over the transistor. The second conductive layer is positioned over the first conductive layer. The second insulating layer is positioned over the first insulating layer. The light-emitting diode includes a first electrode over the second insulating layer, a light-emitting layer over the first electrode, and a second electrode over the light-emitting layer. The second electrode is electrically connected to the second conductive layer. The height of a surface of the first conductive layer on the second conductive layer side is substantially the same as the height of a surface of the first insulating layer on the second insulating layer side. The first insulating layer and the second insulating layer are directly bonded to each other. The second conductive layer is positioned in an opening in the second insulating layer and is electrically connected to the first conductive layer.
