PURPOSE: To make easy the bonding work and improve productivity and bonding property by using unsaturated ester as the bridge agent of bonding agent used for bonding the non-reflective transparent plate to the face plate and adjusting viscosity of bonding agent before it is hardened to a lower value.
CONSTITUTION: Content of unsaturated ester of bridge agent is adjusted to the range of 5W15wt% so that viscocity of bonding agent 3', before it is hardened, for bonding the non-reflective transparent plate 14 to the face plate 2 of the CRT is within the range of 1.5W6.0. The bonding work for the face plate 2 and non-reflective transparent plate 4 can be done esily and productivity and bonding property can also be improved by adjusting viscocity of unsaturated ester to the range of 2.0W3.0 at 25°C.
