PURPOSE: A dynamic focus circuit is provided to prevent waveforms of horizontal and vertical components of a dynamic focus voltage from being distorted by dividing and amplifying the horizontal and vertical components thereof when the horizontal and vertical components thereof are mixed and outputted. CONSTITUTION: A horizontal/vertical processor circuit(62) mixes and supplies horizontal and vertical components of a dynamic focus voltage. A horizontal component amplifier(64) removes and amplifies vertical and horizontal components included in the dynamic focus voltage from horizontal/vertical processor circuit(62), respectively. A vertical component amplifier(66) removes and amplifies horizontal and vertical components included in the dynamic focus voltage from horizontal/vertical processor circuit(62), respectively. An FBT(68) receives and mixes the horizontal and vertical components of the dynamic focus voltage from horizontal component amplifier(64) and vertical component amplifier(66).
