    • In a semiconductor integrated circuit arranged to perform sag compensation for a video signal, an operational amplifier includes a non-inverted input terminal, an inverted input terminal, and an output terminal, in which a video signal is input to the non-inverted input terminal. A first resistor includes a first end connected to the inverted input terminal and a second end being grounded. The output terminal is connected to a first external terminal and the inverted input terminal is connected to a second external terminal. A second resistor includes a first end connected to the output terminal and a second end connected to the inverted input terminal. A first capacitor is disposed between the first external terminal and the second external terminal and connected in parallel to the second resistor, and the second resistor has a resistance value determined based on a capacitance value of the first capacitor.
