Color cathode ray tube |
| 摘要 |
<p>Disclosed is a color cathode ray tube (20) including an in-line electron gun (8), in which a high-resistance film (14) whose resistance R at T DEG C has a resistance-temperature characteristic represented by d(Log R(T))/dT >/= -0.01 at least at a temperature ranging from 20 DEG C to 40 DEG C and is approximately 5 x 10<13> OMEGA or less at about 25 DEG C is formed on the inner wall of the neck (3). <IMAGE></p> |
