Retarder and circular polarizer |
| abstract |
A retarder comprising a substrate, a first optically anisotropic layer formed of a composition comprising a rod-like liquid-crystal compound substantially generating a phase difference of π at 550 nm, and a second optically anisotropic layer formed of a composition comprising a rod-like liquid-crystal compound substantially generating a phase difference of π/2 at 550 nm is disclosed. At least either one of the rod-like liquid-crystal compounds is denoted by Formula (I) Q 1 -L 1 -A 1 -L 3 -M-L 4 -A 2 -L 2 -Q 2 : where Q 1 and Q 2 denote polymerizable groups; L 1 to L 4 denote single bonds or divalent linking groups provided that at least either of L 3 and L 4 represents —O—CO—O—; A 1 and A 2 denote C2-20 spacer groups and M denotes a mesogen group; and an in-plane slow axis of the second layer and an in-plane slow axis of the first layer cross substantially at 60 degrees. |
