1. A thin film transistor comprising:

  • a first blocking layer disposed on a substrate;

    an active pattern disposed on the first blocking layer, wherein the active pattern includes a source region, a drain region, and a channel region disposed between the source region and the drain region;

    a gate electrode disposed on the active pattern, wherein the channel region corresponds to a portion of the active pattern overlapped by the gate electrode; and

    a source electrode connected to the source region, and a drain electrode connected to the drain region,wherein the active pattern includes a first part and a second part, wherein the first part partially overlaps with the first blocking layer, and the first part and the second part have different thicknesses from each other, wherein the second part of the active pattern does not overlap with the first blocking layer.
