Claims20
A liquid crystal composition for a display device, the composition comprising:
- about 20 to about 60 parts, by weight, of at least one compound represented by Chemical Formula 1;
- about 5 to about 18 parts, by weight, of at least one compound represented by Chemical Formula 2;
- about 5 to about 18 parts, by weight, of at least one compound represented by Chemical Formula 3;
- about 5 to about 35 parts, by weight, of at least one compound represented by Chemical Formula 4;
- about 1 to about 8 parts, by weight, of a compound represented by Chemical Formula 5;
- about 1 to about 8 parts, by weight, of a compound represented by Chemical Formula 6;
- and about 1 to about 15 parts, by weight, of a compound represented by Chemical Formula 7:
- with respect to 100 parts by weight of the entire composition,
- wherein R and R′ are each, independently from one another, an alkyl or alkenyl group having 1 to 7 carbon atoms in Chemical Formulas 1 to 7, and
