A tape package includes a body portion including a flexible material, a driving circuit disposed on the body portion, a first sub-connection portion extending from the body portion in a first direction, a first main-connection portion extending from the first sub-connection portion in the first direction, a first lead line including a first end electrically connected to the driving circuit and a second end extending in the first direction, the first end being opposite to the second end and a protrusion extending from the first sub-connection portion in a third direction perpendicular to the first direction on a same plane with the first sub-connection portion. Accordingly, a crack of the lead line may be reduced or effectively prevented.
