Abstract: A thin film transistor including an active layer including a channel, a first connection portion and a second connection portion contacting opposite sides of the channel; and a gate electrode overlapping the channel of the active layer. Further, the active layer includes a first active layer; a second active layer on the first active layer in the first connection portion and the second connection portion of the active layer; and a third active layer contacting the first active layer in the channel and contacting the second active layer in the first connection portion and the second connection portion.
