Abstract
One embodiment of the present invention is a display device including a first insulating layer, a second insulating layer, a first transistor, a second transistor, a first light-emitting diode, a second light-emitting diode, and a color conversion layer. The first insulating layer is over the first transistor and the second transistor. The first light-emitting diode and the second light-emitting diode are over the first insulating layer. The color conversion layer is over the second light-emitting diode. The color conversion layer is configured to convert light emitted from the second light-emitting diode into a light having a longer wavelength. The first transistor and the second transistor each include a metal oxide layer and a gate electrode. The metal oxide layer includes a channel formation region. A top surface of the gate electrode is level or substantially level with a top surface of the second insulating layer.
