Abstract
A cathode-ray tube apparatus (CRT) including a panel glass which has been subjected to no external polishing, and an ultraviolet-curing resin layer provided on the panel glass and having a refractive index which differs from that of the panel glass by not more than 0.8%. The CRT further includes a light-transmitting film provided on the resin layer. Also disclosed is a production method which enables a reduction in the weight of a CRT and an improvement in the explosion-proof performance, which have been demanded with the realization of large-sized CRTs and flat-panel CRTs, and which also makes it possible to produce such CRTs by a simplified process and at a reduced cost.
