Abstract:
1. A light-emitting device, comprising: a pixel region provided on a substrate and including a blue pixel region, a green pixel region, and a red pixel region which correspond to lights of three primary colors of blue, green and red, respectively, the pixel region including: a thin-film transistor having a source electrode, a drain electrode, a gate electrode, a gate insulating film, and an active layer; a light-emitting layer; and a lower electrode and a counter electrode for sandwiching the light-emitting layer therebetween, wherein the active layer includes an oxide; the drain electrode is electrically connected with a part of the light-emitting layer; the thin-film transistor is arranged in the pixel region other than the blue pixel region on the substrate and is provided in at least one of the green pixel region and the red pixel region; and the thin-film transistor is provided with no light-shielding film.
