Abstract

In a liquid crystal display device, a data signal generation unit generates a data signal for controlling the orientation of liquid crystal. A plurality of transistors supply the data signal output from a source IC unit to a plurality of data signal lines of a liquid crystal display panel in a time sharing manner. A gate signal line controls each of the plurality of transistors. A fluctuation suppression unit is connected to the gate signal line that controls any one of the plurality of transistors, and suppresses, in accordance with a gate signal of the connected gate signal line, a voltage fluctuation in the data signal which occurs when another transistor changes from the ON state to the OFF state.
