Embodiment

[0104]

[0105] The materials shown in Table 1 were thoroughly mixed with a three-roll mill, and 1 wt % of a 5 μm spacer was further mixed to obtain sealants of Examples 1 to 4 and Comparative Examples 1 to 3. 2 mg of the prepared sealant was applied in a frame shape around the periphery of a glass substrate having a size of 2 cm x 7 cm using a dispenser. About 7 mg of liquid crystal material was dropped around the center of the glass substrate and completely degassed in vacuum. Place another glass substrate on top of it and adjust their positions. Place the sealed two substrates on a UV irradiation device (100mW / cm 2 ), UV irradiation for 10 seconds. After UV irradiation, an external force was applied to confirm the displacement of the glass substrate and to evaluate the quality of temporary fixation by UV irradiation. Good fixation was confirmed in the examples according to the invention.

[0106] In addition, the UV-irradiated glass substrate was placed in an oven at ...

Abstract

The object of the invention is to provide a sealant for a liquid crystal instillation technique having high precision, durability and reliability without unfavorable effect to liquid crystal. The sealant of the invention is used to manufacture a liquid crystal display by the liquid crystal instillation technique and contains a maleimide compound, an epoxide resin and a latent epoxy curing agent, and does not contain photo-initiation agent. The sealant may be cured for a while by light irradiation and may be cured to an final curing status by heating after light irradiation.

Description

technical field [0001] The present invention relates to a method of manufacturing a liquid crystal display by a liquid-crystal-one-drop-filling process, and more particularly to such a manufacturing method in which the primary sealing of the periphery of the substrate utilizes a sealant in combination with photocuring and heat curing to form. The invention also relates to the sealants used in this method. Background technique [0002] In the conventional method of assembling a relatively small-sized liquid crystal display (hereinafter also referred to as LCD), two transparent substrates with electrodes face each other at a given distance, and their peripheries are bonded with a sealant to form a liquid crystal pool (cell). ), the liquid crystal is introduced into the liquid crystal cell from a liquid crystal inlet formed at a part of the periphery, and the liquid crystal inlet is finally sealed with a sealant to manufacture an LCD. [0003] Since large-sized LCDs have beco...
