  • Patent number: 7075612
    Abstract: An LCD device and a method for manufacturing the same are disclosed. The LCD device includes a substrate; a UV hardening main sealant on the substrate; a UV hardening dummy sealant in a region between the UV hardening main sealant and an edge of the substrate; and a UV shielding part formed in a portion where the UV hardening dummy sealant is overlapped with a cell-cutting line. Also, a UV blocking part is formed under the UV hardening dummy sealant in a portion where the UV hardening dummy sealant is overlapped with a cell-cutting line, so that the sealant formed under the UV blocking part is not hardened, thereby easily cutting the substrate into unit cells.

  • Patent number: 6741322
    Abstract: A production line for manufacture of a LCD device having a plurality of processing devices includes a production line shield being formed of a UV blocking material and positioned along a sealant forming device and an attaching device and between the sealant forming device and the attaching a device; and at least one work lamp that irradiates light in a band other than an ultraviolet band. A UV blocking lamp may be provided above the production line shield. Thus, a sealant is not prematurely hardened, so that the lower substrate is effectively bonded to the upper substrate, and a desired cell gap is maintained between the lower and upper substrates.
