Provided is a liquid crystal display element that can be baked at a low temperature when forming a liquid crystal alignment film capable of imparting an alignment regulating property and a pretilt angle developing property via a photoalignment method. Further provided is a liquid crystal display element in which the liquid crystal pretilt angles are highly stable, and display burn-in hardly occurs even due to long usage. Further provided are a vertical liquid crystal alignment film to be used in the liquid crystal display element, and a liquid crystal aligning agent with which it is possible to provide the vertical liquid crystal alignment film. A liquid crystal aligning agent of the present invention contains: component (A), which is a polymer including (A-1) a site having an isocyanate group and/or a blocked isocyanate group and (A-2) a site having photoreactivity; component (B), which is a compound having, in a molecule, at least two functional groups of at least one type selected from the group consisting of an amino group and a hydroxyl group; and an organic solvent.

Liquid crystal aligning agent containing crosslinking agent and polymer that has site having isocyanate group and/or blocked isocyanate group and site having photoreactivity, liquid crystal alignment film, and liquid crystal display element

The present invention relates to a liquid crystal aligning agent which contains a polymer that has a site having an isocyanate group and/or a blocked isocyanate group, a site having a photoreactive group having photoalignment, and a site having at least one functional group selected from an amino group and a hydroxyl group in each molecule. The present invention provides a liquid crystal display element which enables baking at low temperatures during the formation of a liquid crystal alignment film by a photoalignment method, the liquid crystal alignment film being able to be imparted with alignment regulating property and pretilt angle developing property.
