Abstract: A display apparatus includes a display panel; a touch sensing unit (TSU) on the display panel and including first and second transmission touch lines (TTL); and a touch driving circuit (TDC). The TDC applies first and second touch driving signals (TDS) to the first and second TTL, respectively. The TDC includes first and second sharing switch devices (SSD) respectively connected to the first and second TTL. The first and second SSD are connected to each other. The first TDS has a first voltage level during a first period, and the second TDS has a second voltage level different than the first voltage level during the first period. The TDC is configured to turn on the first and second SSD during a second period after the first period such that the first and second TDSs have a voltage level between the first voltage level and the second voltage level.
