Abstract

An LCD panel and a method for manufacturing the same facilitate more efficient hardening a UV-type hardening sealant suitable for a large size panel. The LCD panel includes first and second substrates, an active region defined on the first substrate and provided with a plurality of TFT's and pixel electrodes, a sealing region defined along a periphery of the active region, a light-shielding region defined on the second substrate other than on the sealing region, and a liquid crystal region between the first and second substrates. The method for manufacturing an LCD panel includes the steps of preparing first and second substrates, forming a plurality of patterns in an active region on the first substrate, forming a UV hardening type sealant along a periphery of the active region, forming a light-shielding layer on the second substrate so as not to shield the sealant, attaching the first and second substrates to each other, and irradiating the sealant with UV-rays to harden the sealant.

Claims (11)

1. A liquid crystal display (LCD) panel comprising:

first and second substrates;

an active region on the first substrate, the active region including a plurality of thin film transistors and pixel electrodes;

a pad region along a periphery of the active region and along a corresponding region of the second substrate, wherein at least one of gate and data lines extends to the pad region of the first substrate;

a sealing region between the active region and the pad region;

sealant in the sealing region between the first and second substrates, the sealant attaching the first substrate and the second substrate to each other;

a light-shielding layer in the pad and active regions except the sealing region on the second substrate, a portion of the light-shielding layer that is in the pad region of the second substrate being located directly above the pad region of the first substrate having one of the gate and data lines extended thereto; and

a liquid crystal layer within the gap and on the active region side of the sealant.

2. The LCD panel of claim 1 , wherein the sealant is an UV-type hardening sealant.

3. The LCD panel of claim 1 ,wherein the light-shielding layer is formed of a light-shielding material.

4. The LCD panel of claim 1 , wherein the light-shielding layer has a matrix arrangement in the active region.
