Problems solved by technology

Also, this will reduce the adhesive force of the sealant 13 bonding the first and second substrates 11a, 11b formed on the boundary between the non-display area 22 and the liquid crystal edge area 21b.
In addition, when the first and second substrates 11a, 11b are bonded to each other, the sealant 13 will be damaged because the adhesive force of the sealant is lowered.

Abstract

The present invention relates to a liquid crystal display (LCD) device and a manufacturing method thereof, the liquid crystal display device comprising: first and second substrates facing each other and having a display area and a non-display area; between the display area and the non-display area A sealant for bonding the first and second substrates formed on the boundary between them; a first alignment layer provided on the display area of ​​the first substrate; and a sealant inside the display area of ​​the first substrate for preventing the first A first barrier for the diffusion of the alignment material of the alignment layer.

Description

[0001] This application claims the benefit of Korean Patent Application No. P2003-69278 filed on October 6, 2003, which is incorporated herein by reference. technical field [0002] The present invention relates to a liquid crystal display (LCD) device, and more particularly, to an LCD device capable of preventing contamination of a sealant and deterioration of adhesive strength due to diffusion of an alignment material and a method of manufacturing the same. Background technique [0003] With the development of information technology, the demand for various display devices is increasing. In particular, much effort has been made to research and develop various flat display devices such as LCDs, plasma display panels (PDPs), electroluminescent displays (ELDs), and vacuum fluorescent displays (VFDs), among others. Among these display devices, the LCD device is most widely used as a substitute for a cathode ray tube (CRT) due to its thin profile, light weight, and low power con...
