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.

CRT panel and a method for manufacturing the same

A funnel for a cathode ray tube, and a cathode ray tube including the funnel are provided. The funnel includes a neck portion whose cross section is vertically long, a first cone portion which extends from the neck portion such that the cross section is vertically long as the neck portion, and is surrounded by a deflection yoke, and a second cone portion which extends from the first cone portion to be enlarged and meets a panel.
