    摘要： The electron gun unit housed in a neck portion of a tube envelope consists of three electron guns corresponding to red, green and blue. The electron gun corresponding to blue is smaller in diameter than the remaining electron guns, and the axes of said electron guns are arranged to form an isosceles triangle in such a manner that the electron gun having a small diameter has its axis on the apex of the isosceles triangle. Fluorescent dots upon which electron beams emitted from said electron guns impinge are substantially in the form of thin rectangles or ellipses which extend substantially at right angles to the beam scanning direction. Adjacent to said fluorescent dots is disposed a shadow-mask having a plurality of rectangularly shaped beam passing holes.
