Abstract
A high performance electric device which uses an adhesive layer over a substrate. A color filter is over a substrate, and an adhesive layer is also located over the substrate and color film. An insulating layer is over the adhesive layer, and thin film transistors cover the insulating film and the color filters. Light emitting elements cover the thin film transistors and emit light through the substrate that is through the adhesive layer and color filter. The substrate may be plastic, thus increasing the heat resistance.
