PURPOSE: An on-cell TSP(Touch Screen Panel) display apparatus is provided to simplify a structure for processing touch information by processing the touch information inputted by a touch key and a touch screen through an information processing unit. CONSTITUTION: A touch screen and key information processing unit(202) transmits a signal to a control unit by determining touch information inputted by a touch screen and a touch key. The touch screen and key information processing unit is installed on an FPCB(Flexible Printed Circuit Board)(250) which is installed on the one end of a touch sensor(265a-265c) corresponding to the touch keys. One end of the FPCB is connected with the touch screen pattern of the touch screen. The touch sensors transmit the touch information inputted by the touch key through channels in the touch screen.
