Title: CRT display device having discharge current limiting resistors in high-voltage supply lines

Abstract: Discharge current limiting resistors are provided in respective high-voltage supply lines for distributing high voltages produced by a high-voltage distributor to the anodes of respective CRTs. As a result, a discharge current coming from a high-voltage capacitor that is part of a total discharge current flowing into a CRT where an abnormal discharge has occurred can be reduced to 1/2 of that in the conventional case and discharge currents coming from coating capacitances of the remaining CRTs that is another part of the total discharge current can be inhibited.
