Abstract:
1. A transparent thin film transistor comprising: a substantially transparent substrate; a gate line in which a thin film of a substantially transparent conductive material and a thin film of a metal material are stacked, a substantially transparent gate insulating layer; a substantially transparent semiconductor active layer; and a source line in which a thin film of a substantially transparent conductive material and a thin film of a metal material are stacked, and a drain electrode including a thin film of a substantially transparent conductive material, said source line and said drain electrode being formed apart from each other and sandwiching said substantially transparent semiconductor active layer, wherein said thin film of said metal material of said source line is stacked on said substantially transparent conductive material of said source line, and said thin film of said substantially transparent conductive material of said gate line is stacked on said thin film of said metal material of said gate line, and wherein a line width of said thin film of said metal material of said gate line and of said thin film of said metal material of said source line is narrower than a line width of said thin film of said substantially transparent conductive material of said gate line and of said thin film of said substantially transparent conductive material of said source line.
