Abstract
Disclosed is a method for fabricating a liquid crystal display panel that has an improved picture quality by preventing stains due to impurities and ionic materials. The method includes the steps of preparing a TFT substrate having a plurality of electrodes; preparing a color filter substrate having a color filter layer, a black matrix layer, and an overcoat layer; forming a groove adjacent an edge of the overcoat layer of the color filter substrate; forming a double sealant at the sides of the groove in the overcoat layer; forming a liquid crystal layer on at least one of the TFT substrate and the color filter substrate; and attaching the TFT substrate to the color filter substrate.

A method for fabricating a liquid crystal display panel, comprising the steps of:
- preparing a TFT substrate having a plurality of electrodes;
- preparing a color filter substrate having a color filter layer, a black matrix layer, and an overcoat layer;
- forming a groove adjacent an edge of the overcoat layer of the color filter substrate;
- forming a double sealant at the sides of the groove in the overcoat layer;
- forming a liquid crystal layer on at least one of the TFT substrate and the color filter substrate;
- and
- attaching the TFT substrate to the color filter substrate.
A method for fabricating a liquid crystal display panel, comprising the steps of:
- preparing a first substrate having a groove on a surface at the periphery;
- forming sealant ridges at both sides of the groove on the first substrate;
- preparing a second substrate;
- coating a liquid crystal on at least one of said surface of the first substrate and a surface of the second substrate;
- and
- attaching the first substrate to the second substrate so that the surface of the first substrate having the groove faces the second substrate and that the top of each sealant ridge on the first substrate is attached to the second substrate to seal the liquid crystal.
A liquid crystal display panel, comprising:
- a first substrate having a groove on a surface at its periphery;
- a second substrate that is coupled to the first substrate via sealants, the surface of the first substrate having the groove facing the second substrate, the sealants being disposed along and at both sides of the groove;
- and
- a liquid crystal between the first substrate and the second substrate, the liquid crystal being sealed via the sealants.
