Abstract
Disclosure is related to a cathode ray tube including a panel forming a fluorescent layer therein, and a funnel connected to a panel and including an electron gun and a deflection yoke mounted inside and near the neck portion thereof, respectively, which satisfies the following equation: .theta.RL=1 to 1.3 where .theta. denotes a deflection angle in degrees of an electron beam emitted from the electron gun, and RL denotes the distance in millimeters between the outlet of the electron gun mounted in the neck portion and the reference line which is the boundary between the deflection region where the electron beam emitted from the electron gun is deflected by the deflection yoke and the linear region where the electron beam moves linearly. The cathode ray tube can prevent the electron beam emitted from the electron gun from colliding with the inner surface of the funnel and mislanding in the corner areas of the fluorescent layer.
