A gate electrode(235) is formed in the same shape of the shape of the organic semiconductor layer on the gate insulating layer. A first protection layer(240) having a gate contact hole is formed on the gate electrode. A gate line(250) is formed on the first protection layer and comes in contact with the gate electrode through the gate contact hole. The gate line crosses the data line in order to define a pixel region.
