LIGHT-EMITTING DEVICE USING OXIDE SEMICONDUCTOR THIN-FILM TRANSISTOR AND IMAGE DISPLAY APPARATUS USING THE SAME
First Claim
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 a region other than the blue pixel region on the substrate; and
the thin-film transistor is provided with no light-shielding film.
