Abstract

The invention relates to hardening equipment and a method for manufacturing a liquid crystal display panel. The hardening equipment comprises a response cabin, a workbench, an ultraviolet lamp and a light barrier, wherein the workbench is positioned at the bottom of the response cabin and is provided with a first area and a second area which is enclosed by the first area; the first area corresponds to a non-display area of the panel; the second area corresponds to a display area of the panel; the ultraviolet lamp is positioned on the top of the response cabin and is used for irradiating the workbench; the light barrier is positioned below the ultraviolet lamp and is used for shielding the second area of the workbench; and the workbench is provided with a heating device. By using a method of arranging the heating device on the workbench, the hardening equipment of the invention can perform heat treatment on an adhesive at the same time in the process of hardening the adhesive by using ultraviolet rays, thereby overcoming the defect of the increasing of equipment cost caused by the large scale of liquid crystal panels in the prior art.

Description

technical field [0001] The invention belongs to the fields of liquid crystal display devices and manufacturing equipment, and in particular relates to a curing device used in the manufacturing process of a liquid crystal display device and a method for manufacturing a liquid crystal display panel using the curing device. Background technique [0002] A liquid crystal display device (Liquid Crystal Display, referred to as LCD) is a main flat panel display device (Flat Panel Display, referred to as FPD). [0003] Liquid crystal display devices are classified into vertical electric field type liquid crystal display devices and horizontal electric field type liquid crystal display devices according to the direction of an electric field for driving liquid crystals. Vertical electric field type liquid crystal display devices include: twisted nematic (TwistNematic, referred to as TN) type liquid crystal display devices; horizontal electric field type liquid crystal display devices ...
