Abstract

A liquid crystal display panel includes a TFT substrate, a color filter (CF) substrate opposed to the TFT substrate, a sealant disposed between the TFT substrate and the CF substrate and disposed between portions of both the substrates located immediately outside display regions thereof, and a liquid crystal layer disposed between the TFT substrate and the CF substrate. The CF substrate is provided with a light-shielding layer at a portion located immediately outside its display region. The light-shielding layer is provided with a slit at a region that coincides with a line on the TFT substrate.

Claims (18)

1. A panel comprising:

a first substrate;

a second substrate opposed to the first substrate; and

a sealant disposed between the first substrate and the second substrate and disposed between portions of the first and second substrates located immediately outside display regions of the first and second substrates; wherein

at least the portion of the first substrate is provided with a plurality of spaced wires arranged in a non-uniform manner and exhibiting a light blocking effect;

the portion of the second substrate is provided with a light-shielding layer; and

the light shielding layer is provided with a plurality of slits in one-to-one correspondence with the plurality of spaced wires so that portions of the sealant coinciding with the plurality of spaced wires are entirely irradiated with light.

2. The panel of claim 1 , further comprising a liquid crystal layer disposed between the first substrate and the second substrate.

3. The panel of claim 2 , wherein the sealant has a loop configuration.

4. The panel of claim 1 , wherein the sealant is made of a composite containing a photocuring agent.

5. The panel of claim 2 , further comprising a barrier arranged inside the sealant and so as to extend along the sealant, and the surface of the barrier near the sealant is inclined relative to the surfaces of the first and second substrates.

6. A method for manufacturing a panel including a first substrate, a second substrate opposed to the first substrate, a sealant disposed between the first substrate and the second substrate and disposed between portions of the first and second substrates located immediately outside display regions of the first and second substrates, and a liquid crystal layer disposed between the first substrate and the second substrate, said method comprising the steps of:

forming a plurality of spaced wires arranged in a non-uniform manner and exhibiting a light blocking effect on at least the portion of the first substrate;

forming a light-shielding layer on the portion of the second substrate, where the light-shielding layer is provided with a plurality of slits in one-to-one correspondence with the plurality of spaced wires so that portions of the sealant coinciding with the plurality of spaced wires are entirely irradiated with light;

applying an uncured sealant containing a photocuring agent to the portion of one of the first and second substrates in loop form;

dropping a liquid crystal material onto a region of said one of the first and second substrates surrounded by the uncured sealant;

bonding the first and second substrates together; and

applying light through both the first and second substrates to the uncured sealant to cure the uncured sealant, thereby forming the sealant.
