1. A display device comprising:
a display panel including:
scanning signal lines;data signal lines;pixel electrodes; andswitching elements,
each of the switching elements having (i) one terminal connected with one of the pixel electrodes and (ii) another terminal connected with one of the data signal lines,each of the scanning signal lines turning on/off switching elements corresponding thereto,the each scanning signal line forming one of rows together with the switching elements connected thereto, and pixel electrodes respectively connected to these switching elements; a scanning signal line driving circuit including a plurality of shift registers each provided so as to correspond to each of the rows, the scanning signal line driving circuit outputting a scanning signal for turning on the switching elements in the each row; a data signal line driving circuit outputting a data signal in accordance with an image to be displayed; a dummy scanning signal line provided for an outermost row located at an outermost position from which scanning by use of the scanning signal starts, the dummy scanning signal line being driven by a gate start pulse inputted into a shift register corresponding to the outermost row located at the outermost position,
the gate start pulse driving the dummy scanning signal line has a voltage level allowing the switching element to be turned on/off,the gate start pulse driving the dummy scanning signal line is set at the voltage level by a buffer; and a control device generating the gate start pulse and a clock for driving the scanning signal line driving circuit,
the control device including the buffer for generating the gate start pulse,the dummy scanning signal line is connected to a signal line connecting the control device with the scanning signal line driving circuit; andthe gate start pulse is inputted into the scanning signal line driving circuit and the dummy scanning signal line via the signal line.
