Claim Text:
1. A display device having safety functions, comprising: a display panel forming unit pixel regions by intersecting a plurality of data lines with a plurality of gate lines; a first driving channel including a first data driving unit connected to one sides of the data lines and a first gate driving unit connected to one sides of the gate lines; a second driving channel including a second data driving unit connected to the other sides of the data lines and a second gate driving unit connected to the other sides of the gate lines; a first switching unit including a plurality of first switching elements which allow or block a signal connection between the data lines and the first data driving unit; a second switching unit including a plurality of second switching elements which allow or block a signal connection between the gate lines and the first gate driving unit; a third switching unit including a plurality of third switching elements which allow or block a signal connection between the data lines and the second data driving unit; and a fourth switching unit including a plurality of fourth switching elements which allow or block a signal connection between the gate lines and the second gate driving unit, wherein gate electrodes of the plurality of first switching elements are connected to each other, and at least a portion of signals input to the first driving channel is input to the gate electrodes of the first switching elements connected to each other, to thereby allow the first switching unit to be switched on; gate electrodes of the plurality of second switching elements are connected to each other, and at least a portion of the signals input to the first driving channel is input to the gate electrodes of the second switching elements connected to each other, to thereby allow the second switching unit to be switched on; gate electrodes of the plurality of third switching elements are connected to each other, and at least a portion of signals input to the second driving channel is input to the gate electrodes of the third switching elements connected to each other, to thereby allow the third switching unit to be switched on; gate electrodes of the plurality of fourth switching elements are connected to each other, and at least a portion of the signals input to the second driving channel is input to the gate electrodes of the fourth switching elements connected to each other, to thereby allow the fourth switching unit to be switched on; and the display panel is driven by one of the first driving channel and the second driving channel.
