1. A panel defining a front exterior of a cathode ray tube having a funnel, the panel comprising:
- a display portion defining a distal end of the panel;
a curved lateral wall extending from the display portion toward the funnel, wherein at least an end of the lateral wall is joined to the funnel;
a phosphor screen formed on an inner surface of the display portion, the phosphor screen including RGB phosphor pixels and a black matrix layer between the RGB phosphor pixels; and
a light transmission compensating member for compensating for differences in brightness of the phosphor screen, the light transmission compensating member being provided on an outer surface of the display portion while varying light transmission at a center and a periphery of the display portion.

Abstract
A panel defining a front exterior of a cathode ray tube has an inner surface overlaid with a phosphor screen, and an outer surface overlaid with a tinted coating layer, wherein the tinted coating layer varies light transmission at the center and the periphery of the panel by being dark at the center and gradating brighter toward the periphery thereby preventing a difference in brightness of the panel between the center and the periphery thereof due to incremental growth in the volume of a black matrix and in the thickness of the panel toward the periphery.
