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.
Claims28
A liquid crystal display device, comprising:
- 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.
A method for manufacturing an LCD device comprising:
- preparing first and second substrates;
- forming a UV shielding part in a dummy region on one of first and second substrates;
- forming a UV hardening main sealant on the substrate on which the UV shielding part is formed;
- forming a UV hardening dummy sealant on the substrate between the UV hardening main sealant and an edge of the substrate;
- applying a liquid crystal on one of the first and second substrates;
- attaching the first and second substrates;
- irradiating UV light onto the UV hardening main sealant and UV hardening dummy sealant;
- and
- cutting the substrates into unit cells.
