PURPOSE:To prevent the dispersion of liquid-tightness by providing a pre-airtight fixing section at an airtight fixing section between the outer surface of a funnel and an annular radiating body, heating and hardening it, then injected an adhesive agent into a main airtight fixing section. CONSTITUTION:An annular radiating body 7 is fitted via an airtight fixing section 20 so as to surround the outer surface of a funnel 3, a transparent plate body 6 is fitted via an airtight fixing section 10 in front of the radiating body 7, and a space between them is sealed with a heat cooling medium liquid 11 to form a projecting CRT device. In this case, the airtight fixing section 20 is formed with a pre-airtight fixing section 21 and a main airtight fixing section 22, first the pre-airtight fixing section 21 is coated with an adhesive agent having relatively high viscosity, the annular radiating body 7 is fitted to the pre-airtight fixing section 21, which is heated and hardened, then an adhesive agent having relatively low viscosity is injected into the main airtight fixing section 22 to fix it. Accordingly, reliable liquid-tightness with no disper sion can be obtained and reliability can be improved. |
