Disclosed is a color CRT (Cathode Ray Tube) integrated with deflection circuit. The color CRT includes a sync signal separation and deflection circuit board attached on at least a portion of the color CRT. The sync signal separation and deflection circuit board includes a sync signal separation circuit for separating sync signal from video signal to regenerate video signal into the same contents, a horizontal deflection circuit for impressing horizontal deflection current onto a horizontal deflection coil and a vertical deflection circuit for impressing vertical deflection current onto a vertical deflection coil. The color CRT, which has the sync signal separation and deflection circuit attached on at least a portion of the color CRT, allows a one-to-one matching of the deflection circuit and a deflection yoke by removing the causes of DY fluctuation due to the change of set condition. Moreover, the color CRT reduces a manufacturing cost by mass production of the deflection circuit and the deflection yoke and facilitates improvement of quality.
