PURPOSE: A circuit for removing high-frequency interference is provided, which effectively restricts surge noise caused by high-frequency interference in a high-resolution monitor using high-frequency signals. CONSTITUTION: A circuit for removing high-frequency interference includes a field effect transistor(Q1) whose gate receives a horizontal drive signal from an MCU to amplify the signal, a diode(D2) connected to the drain of the field effect transistor to attenuate noise contained in the signal, and a capacitor(C3) connected in parallel with the diode. The first and second beads(BD1,BD2) are serially connected to both ends of the diode. The first and second beads attenuate surge noise that is amplified through the field effect transistor.
