Abstract:
1. An electroluminescence display device comprising: a substrate having an insulating surface; a first signal line extending in a first direction over the substrate; a second signal line extending in a second direction over the substrate wherein a pixel is defined at an intersection between the first signal line and the second signal line; a first thin film transistor formed in said pixel over said substrate, said thin film transistor comprising an active layer comprising crystalline silicon formed over said substrate and a gate electrode adjacent to the active layer; an insulating film formed over the first thin film transistor; a first electrode formed over the substrate in a region where the insulating film is removed; a conductive layer formed over the insulating film wherein the first electrode is electrically connected to the thin film transistor through the conductive layer; an electroluminescence layer comprising an organic material formed over said first electrode; a second electrode formed over said electroluminescence layer; and a peripheral driving circuit comprising a second thin film transistor formed over said substrate, said peripheral driving circuit electrically connected to said first signal line wherein said second thin film transistor comprises an active layer comprising crystalline silicon formed over said substrate and a gate electrode adjacent to the active layer.
