Abstract: A thin film transistor and a display panel having the same are provided. A display panel includes a substrate, an active layer disposed over the substrate and including a source region, a drain region, and a middle region between the source region and the drain region, and a gate electrode over the active layer and disposed overlapping with the middle region, and the active layer includes a plurality of holes disposed symmetrically with respect to the middle region. The display panel can improve its reliability owing to heat dissipation paths through the plurality of holes.
