Abstract
Disclosed is a liquid crystal display (LCD) device. The LCD device includes a first substrate and a second substrate facing each other, a liquid crystal layer between the first substrate and the second substrate, an alignment layer on at least one of the first and second substrates for alignment of liquid crystals in the liquid crystal layer, and a sealant in an edge area of each of the first and second substrates to bond the first substrate to the second substrate, the sealant including a diene compound.
Claims20
A liquid crystal display (LCD) device, comprising:
- a first substrate and a second substrate facing each other;
- a liquid crystal layer between the first substrate and the second substrate;
- an alignment layer on at least one of the first substrate and the second substrate for alignment of liquid crystals in the liquid crystal layer, the alignment layer including a maleimide functional group;
- and
- a sealant in an edge area of each of the first substrate and the second substrate to bond the first substrate to the second substrate, the sealant including a diene compound, wherein the sealant contacts the alignment layer to chemically bond the diene compound to the maleimide functional group of the alignment layer, and wherein the diene compound is represented by Chemical Formula 1:
- where R1, R2, and R3 are independently one among hydrogen, a halogen atom, a phenyl group, an alkyl group of C1˜C9, an alkoxy group of C1˜C9, a vinyl group of C2˜C4, and an acetyl group of C2˜C4, and R4 is one among a phenyl group, an alkyl group of C1˜C9, an alkoxy group of C1˜C9, a vinyl group of C2˜C4, and an acetyl group of C2˜C4.
