Beschreibung
Zusammenfassung:	A display device includes: thin film transistors (TFTs) on a substrate, pixel electrodes (PEs) respectively connected to the TFTs, common electrode blocks (CEBs) on the substrate, each CEB forming an electric field with a respective PE, touch sensing lines (TSLs) respectively connected to the CEBs, a lower planarization layer (PL) between the TFTs and the TSLs, an upper PL between the TSLs and one of: the PEs and the CEBs, an upper protective film between the PEs and the CEBs, and pixel contact holes extending through the lower PL and the upper PL to expose respective drain electrodes of the TFTs, wherein a side surface of each of the lower PL and the upper PL, exposed through the pixel contact holes, contacts one of: the upper protective film and the PEs.
