Patent ID: 7977741

Claim:
A flexible semiconductor device including a thin film transistor, comprising: a resin film; a second metal layer embedded in the resin film and functioning as a gate electrode, wherein the resin film has a via connected to the second metal layer embedded in the resin film, wherein a third metal layer including a gate line is formed on a lower surface of the resin film, and the gate line is electrically connected to the gate electrode through the via; an inorganic insulating layer formed on an upper surface of the second metal layer and functioning as a gate insulating film; and a first metal layer formed on an upper surface of the resin film and functioning as source/drain electrodes, wherein a semiconductor layer is formed on the gate electrode with the inorganic insulating layer interposed therebetween, and the semiconductor layer is provided so as to be in contact with the source/drain electrodes.
