An alignment film having particularly good orientation and less coloring is provided. A photo-alignment agent containing at least one polymer having photo-alignment ability as an A component and at least one polymer having a liquid crystal temperature range of 100 to 300 ° C. as a B component. Preferred examples of the component A are polyamic acid or polyimide having a photosensitive group -N = N- or the like in the main chain, and preferred examples of the component B are liquid crystal having a straight chain alkylene structure having 6 to 20 carbon atoms in the main chain. Of polyamic acid or polyimide. [Selection figure] None |
