Abstract: A display device includes a bottom electrode on a substrate, and including a first electrode portion and second electrode portions on sides of the first electrode portion, a first insulating layer on the substrate and the bottom electrode, an active layer on the first insulating layer, and including a channel region on the first electrode portion and a source and a drain region on the second electrode portions, a gate insulating layer on the channel region, and exposing the source and the drain region, and a gate electrode on the gate insulating layer, and overlapping the channel region. The first insulating layer and the active layer includes a valley in a corresponding area between the first electrode portion and the second electrode portions. The gate insulating layer includes an end positioned on the valley of the active layer and has a length greater than the gate electrode.
