摘要： A horizontal deflection circuit which enables various kinds of correction. One end of a first parallel circuit having a first switching element (11), a first damper diode (12) and a first resonance capacitor (13) connected mutually in parallel is grounded, and the other end of the first parallel circuit is connected to one end of a second parallel circuit having a second switching element (21), a second damper diode (22) and a second resonance capacitor (23) connected mutually in parallel. The other end of the first parallel circuit is connected to a DC power supply terminal via a primary winding of a fly-back transformer (6). The other end of the second parallel circuit is grounded via a series circuit made up of a horizontal deflecting coil (4) and an S-distortion correction capacitor (5), and a connection nod between the horizontal deflecting coil (4) and the S-distortion correction capacitor (5) is grounded via a parallel circuit made up of an intermediate pin-cushion distortion correcting circuit (60) and a horizontal linearity correcting circuit (70). Switching element control means (40) for switching the first switching element (11) by a horizontal drive signal and for controlling off-start timing and off-period of the second switching element (21) is provided.
