Abstract
A UV irradiating device and a method of manufacturing an LCD device using the same are disclosed. The UV irradiating device includes a UV light source part having a UV lamp and a reflecting plate, a support supporting the UV light source part, and a stage on which a substrate is placed, the UV light source being irradiated at a tilt angle upon the substrate. The UV is irradiated upon the substrate on which the UV sealant is formed, so that a sealant can be hardened even if a light-shielding layer or a metal line layer are formed between a UV irradiating surface and the UV sealant.
