A display panel includes a semiconductor layer formed on a substrate, a first insulating layer formed on the semiconductor layer, a gate line including a gate electrode and formed on the first insulating layer, a second insulating layer formed on the gate line, and a data line including a source electrode and a drain electrode formed on the second insulating layer. The second insulating layer covered with the drain electrode and the data line may be thicker than the second insulating layer not covered with the drain electrode and the data line. The data conductors are disposed on a higher interlayer insulating layer than the others such that diffused or migrating aluminum material is placed on the lower interlayer insulating layer to be prevented from being connected to the data conductors.
