Process for vertical alignment of rod-like liquid crystal molecules |
摘要 |
A process for alignment of rod-like liquid crystal molecules comprises the steps of: forming an orientation layer for vertical alignment on a support; and forming a liquid crystal layer containing rod-like liquid crystal molecules on the orientation layer to align the rod-like liquid crystal molecules at an average inclined angle of 50 to 90°. The liquid crystal layer further contains a compound represented by the formula (I): <paragraph lvl="0"><in-line-formula>(Hb-L1-Cy1-L2-)nCy2 (I) </in-line-formula>wherein Hb is an aliphatic group having 6 to 40 carbon atoms or an siloxanoxy group substituted with an aliphatic group having 6 to 40 carbon atoms, each of L1 and L2 is a single bond or a divalent linking group, Cy1 is a divalent aromatic group or a divalent heterocyclic group, n is 2, 3 or 4, and Cy2 is an n-valent aromatic group or an n-valent heterocyclic group.
