Abstract
A sealant that can be used in a liquid crystal display device without contaminating the liquid crystal layer is presented. The sealant includes an acrylic-based compound having at least two acryl groups per molecule and an epoxy-based compound having an epoxy group and a dihydrazide compound. A liquid crystal display using the sealant is provided. The liquid crystal display includes a first substrate having a display area, a second substrate on the first substrate and a liquid crystal layer interposed between the first and second substrates. A sealant pattern is formed on any one of the first and second substrates in an outer portion of the display area by using the sealant.
Claims14
A sealant comprising:
- an acrylic-based compound comprising at least two acryl groups per molecule;
- and
- an epoxy-based compound comprising an epoxy group;
- wherein the acrylic-based compound comprises a compound having a molecular weight in a range of about 100,000 to about 500,000 and a chemical formula 4:
- wherein n is equal to or greater than 1.
A liquid crystal display comprising:
- a first substrate that has a display area and includes a data line thereon;
- a second substrate on the first substrate and including a common electrode;
- a liquid crystal layer interposed between the first and second substrates;
- and
- a sealant pattern formed on at least one of the first and second substrates between the data line and the common electrode in an outer portion of the display area so as to combine the first and second substrates, and including an acrylic-based compound,
- wherein the acrylic-based compound comprises a compound having a molecular weight in a range of about 100,000 to about 500,000, and a chemical formula 4:
- wherein n is equal to or greater than 1.
