Abstract
A method of fabricating a liquid crystal display device includes forming a thin film transistor array on an active area of a first substrate, forming a color filter layer and a black matrix layer on a second substrate, forming a sealant along a peripheral portion of the second substrate, bonding the first and second substrates, and hardening the sealant by exposure to light, wherein the black matrix layer and the sealant are offset and do not overlap each other.
Claims22
A method of fabricating a liquid crystal display device, comprising:
- forming a thin film transistor array on an active area of a first substrate;
- forming a color filter layer and a black matrix layer on a second substrate;
- forming a sealant along a peripheral portion of the second substrate;
- bonding the first and second substrates;
- hardening the sealant by exposure to light;
- and
- further hardening the sealant by exposure to heat after hardening the sealant by exposure to light,
- wherein the black matrix layer and the sealant are offset and do not overlap each other and a width of the black matrix is greater than that of the sealant so as not to expose the black matrix to the light used to harden the sealant,
- wherein the sealant includes a UV and thermo-hardening sealant material.
A method of fabricating a liquid crystal display device, comprising:
- forming a thin film transistor within an active area of a first substrate;
- forming a color filter layer and a black matrix on a second substrate;
- forming a photo-hardening and thermo-hardening sealant along a periphery of the active area;
- bonding the first and second substrates;
- hardening the sealant by exposure to light;
- and
- further hardening the sealant by exposure to heat after hardening the sealant by exposure to light,
- wherein the active area is bounded by a metal pattern having a plurality of through-holes, the black matrix layer and the sealant are offset and do not overlap each other, and a width of the black matrix is greater than that of the sealant so as to form an irradiation path, wherein the black matrix is not exposed to the light used to harden the sealant.
