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.
Claims15
A display apparatus, comprising:
- a first substrate and a second substrate facing each other;
- an alignment layer on at least one of the first substrate and the second substrate, an alignment direction of the alignment layer being configured by first ultraviolet rays;
- and
- a sealant configured to bond the first substrate to the second substrate,
- wherein the sealant includes a compound that reacts with the alignment layer, and the compound of the sealant is chemically bonded to the alignment layer by second ultraviolet rays,
- wherein the sealant includes a compound 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.
