A correction waveform generation circuit that generates the correction waveform necessary for convergence correction, a convergence adjustment circuit that adjusts the correction waveform generated by this correction waveform generation circuit so as to obtain the desired convergence, and adjustment by this convergence adjustment circuit. A correction current generation circuit generates a correction current to be supplied to the convergence coil from the corrected correction waveform, and stops generation of the correction waveform or correction current for a certain period of time immediately after the power is turned on to prevent transient convergence fluctuations. A convergence circuit consisting of a miute circuit.
