Abstract

PROBLEM TO BE SOLVED: To provide constitution and facility which prevent the mispositioning of glass substrates and the defect of a panel sealing gap by improving the seal packing of a pressurization type UV irradiation device in a seal curing process step of a liquid crystal panel. SOLUTION: The glass substrates are pressed with the seal packing and a pressurizing section is formed by installing a chamber above the glass substrates placed on a surface plate and air is applied to the pressurizing section, by which pressure is exerted to the glass substrates. The panel seal is irradiated with UV rays from a UV lamp and is thus cured in the state of forming the gap of the panel seal by exerting the pressure to the glass substrates. The pressure in the pressurizing section is thereafter reduced and the chamber ascends, thereby peeling the glass substrates and the seal packing. Teflon (R) is formed on the surface of the seal packing of this time, by which the peelability is improved.

[0007]

In order to solve the above-mentioned problems, the structure and equipment of the seal packing of the present invention is to install the chamber 2 on the glass substrate 4 placed on the surface plate 5. Then, the glass substrate 4 is pressed by the seal packing 3 to form the pressurizing portion 1, and air is applied to the pressurizing portion 1 to apply pressure to the glass substrate 4. U is applied with pressure applied to the glass substrate 4 to form the panel seal 6 gap.
Ultraviolet rays 9 are irradiated from the V lamp 8 to cure the panel seal 6. Then, the pressure in the pressurizing unit 1 is reduced, the chamber 2 is raised, and the glass substrate 4 and the seal packing 3 are separated. At this time, the Teflon 7 is formed on the surface of the seal packing 3 to improve the peeling property.
