Abstract
A color cathode ray tube includes a panel portion with its inner surface coated with a phosphor film; and an in-line type electron gun having a cathode, a control electrode, an accelerating electrode, a focus electrode, and an anode for projecting three electron beams toward the phosphor film. The in-line type electron gun projects the three electron beams substantially in parallel to each other in a plane perpendicular to the major axis of the screen.
