• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

PROBLEM TO BE SOLVED: To provide a sealing material hardening method and hardening device capable of preventing deviation between a pair of substrates stuck together, obtaining a fixed ultraviolet ray illuminance distribution even in the irradiation area of a wide range, enabling the easy separation of the substrate and a mask or the like and improving the production efficiency and quality of a liquid crystal panel. SOLUTION: An ultraviolet ray shield plate 2 is positioned and carried to an overlay position, the position data of the ultraviolet ray shield plate 2 at the overlay position are stored and it is carried to a positioning position. A liquid crystal material 1c is dropped to one substrate 1a, an ultraviolet ray setting sealing material 1b is applied on the other substrate 1d, the pair of the substrates 1 stuck together are positioned and carried to the overlay position, and the position data of the pair of the substrates 1 at the overlay position are stored. These position data are compared with each other and the position of the pair of the substrates 1 is adjusted. The ultraviolet ray shield plate 2 is overlaid on the pair of the substrates 1, both 1 and 2 are irradiated with ultraviolet rays and the sealing material 1b applied on the other substrate 1 is cured.
