PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of improving the display quality of a liquid crystal display panel by suppressing a fluctuation in the output voltage level of a liquid crystal driving power source circuit due to a high-frequency component generated by a timing generation circuit even if impedance resistance is increased by each wiring resistance by ITC wiring. SOLUTION: A first feedback resistor Rb electrically connected at one end side to an output terminal of an operational amplifier 21 and a second feedback resistor Ra connected to the other end side of the first feedback resistor Rb to constitute a series circuit, and a capacitor C2 connected in parallel to the first feedback resistor Rb are arranged in a driving voltage adjustment circuit 4. Also, the resistance value of the second feedback resistor Ra is set smaller than that of the first feedback resistor Rb. An inversion input terminal of the operational amplifier 21 is connected to the connection point of the first feedback resistor Rb and the second feedback resistor Ra. COPYRIGHT: (C)2006,JPO&NCIPI
