摘要
A novel liquid crystalline compound by the formula: Z1-(CH2)n-L1-P1-L2-P2-L3-P3-L4-(CH2)m-Z2 wherein Z1 and Z2 are each independently a group represented by any one of formulas (2), (3) and (4) below, L1, L2, L3, and L4 each independently indicate direct bond or are a group represented by any of -O-, -O-CO-, or -CO-O-, P1 and P2 are each independently a group represented by formula (5) below, and P3 indicates direct bond or is a group represented by formula (5) below, n and m are each independently an integer of 0 to 8; CHEM wherein X is selected from the group consisting of hydrogen, methyl, or halogen and provides an optical film with an excellent capability of retaining the aligned liquid crystal orientation which has been fixed and in mechanical strength.
