Abstract

A liquid crystal display that is less vulnerable to signal line corrosion due to infiltration of moisture is presented. The display includes: a first display panel and a second display panel facing each other; a sealant disposed between the first display panel and the second display panel to define a sealant region and couple the first display panel and the second display panel to each other; a blocking member disposed between the first display panel and the second display panel and neighboring the sealant; and a liquid crystal interposed between the first display panel and the second display panel, and disposed in the sealant region. The blocking member includes silicone formed from a silane derivative having at least one butyrate.

Claims (29)

1 . A liquid crystal display comprising:

a first display panel and a second display panel facing each other;

a sealant disposed between the first display panel and the second display panel to define a sealant region and couple the first display panel to the second display panel;

a blocking member disposed between the first display panel and the second display panel and neighboring the sealant, wherein the blocking member includes silicone formed from a silane derivative having at least one butyrate; and

a liquid crystal layer interposed between the first display panel and the second display panel and disposed in the sealant region

2 . The liquid crystal display of claim 1 , wherein

the silane derivative has Chemical Formula 1:

wherein R1 and R2 are same as or different from each other, and are selected from an alkyl group with 1 to 5 carbons.

3 . The liquid crystal display of claim 2 , wherein

the first display panel includes

a plurality of gate lines extending parallel to each other according to a first direction, and

a plurality of data lines extending parallel to each other and intersecting the gate lines, and

the blocking member includes at least one of

a first blocking member overlapping the gate lines, and

a second blocking member overlapping the data lines.

4 . The liquid crystal display of claim 2 , wherein

at least one of R1 and R2 of an alkyl group of Chemical Formula 1 is combined with at least one functional group selected from

a group consisting of an amide group, an ester group, an ether group, a sulfide group, a sulfoxide group, a hydroxy group, an imide group, an aza group, an amine group, an azo group, an aldehyde group, a carboxylic acid group, an anhydride group, a halide group, and a urea group.

5 . The liquid crystal display of claim 1 , wherein the blocking member is formed outside the sealant region.

6 . A method for manufacturing a liquid crystal display comprising:

forming a first display panel including a plurality of signal lines, a thin film transistor connected to the signal lines, and a pixel electrode connected to the thin film transistor;

forming a second display panel including a common electrode;

forming a liquid crystal layer between the first display panel and the second display panel;

coupling the first display panel to the second display panel using a sealant; and

forming a blocking member between the first display panel and the second display panel along an edge of the second display panel, wherein the blocking member includes a silicone formed from silane derivatives having at least one butyrate.

7 . The method of claim 6 , wherein

the silane derivative has Chemical Formula 1:

wherein R1 and R2 are same as or different from each other, and are selected from an alkyl group with 1 to 5 carbons.

8 . The method of claim 6 , wherein forming the blocking member comprises forming the blocking member outside a sealant region defined by the sealant.
