<P>PROBLEM TO BE SOLVED: To provide an alignment layer having reduced irregularity like interference fringes. <P>SOLUTION: The alignment layer comprises a composition containing: a first polymer having a repeating unit having at least one hydrophilic group selected from a carboxyl group and its salt, sulfonic acid group and its salt, amino group and its salt, phosphoric acid group and its salt, phosphonic acid group and its salt, phosphinic acid group and its salt, hydroxyl group, amide group and sulfonamide group; and a second polymer having a repeating unit having an aromatic group. The mass proportion (r1) of the first polymer is higher than the mass proportion (r2) of the second polymer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
