Abstract
A light-emitting device which includes a semiconductor layer; a first insulating layer over the semiconductor layer; a gate electrode and a first conductive layer over the first insulating layer; a second insulating layer over the gate electrode and the first conductive layer; source and drain electrodes and a second conductive layer over the second insulating layer; a third insulating layer over the source and drain electrodes and the second conductive layer; a first electrode and a third conductive layer over the third insulating layer; a planarization film covering an end portion of the first electrode; an electroluminescent layer over the first electrode; and a second electrode over the electroluminescent layer and the planarization film is provided. The second electrode is electrically connected to the third conductive layer through an opening portion provided in the planarization film. The opening portion overlaps with the first, second, and third conductive layers.
