Display device

A display device, comprising:

• a substrate;
• a main active layer positioned on the substrate, and comprising a channel area, a first conductorized area positioned on a first side of the channel area, and a second conductorized area positioned on a second side of the channel area;
• a first sacrificial active layer positioned on the first conductorized area of the main active layer, the thickness of the first sacrificial active layer being lower than the thickness of the main active layer;
• a second sacrificial active layer positioned on the second conductorized area of the main active layer, the thickness of the second sacrificial active layer being lower than the thickness of the main active layer;
• a gate insulating film positioned on the channel area of the main active layer;
• a first electrode positioned on the first sacrificial active layer, a portion of the first electrode overlapping the first conductorized area of the main active layer;
• a second electrode positioned on the second sacrificial active layer, a portion of the second electrode overlapping the second conductorized area of the main active layer;
• and
• a third electrode positioned on the gate insulating film and overlapping the channel area of the main active layer.
