ABSTRACT:
In a flat type color cathode ray tube, in using of a tint or a dark tint panel capable of improving contrast characteristics of a screen and reducing production processes, namely, having the conventional coating process reduction advantage, by optimizing a horizontal pitch and a transmissivity of a shadow mask and a transmissivity of a screen in order to solve a brightness balance deterioration problem at the circumference portion of the screen due to a glass transmissivity difference, it is possible to maintain inner impact resistance and howling characteristics of the shadow mask, in addition, by improving a circumference portion transmissivity of the shadow mask and a screen transmissivity, it is possible to improve a brightness balance at the circumference portion and a quality of the screen.
