The present invention provides a liquid crystal display element, a liquid crystal composition and a liquid crystal aligning film with the characteristics of short response time, high voltage holding ratio, low threshold voltage, high contrast ratio, long lifespan, low flicker rate and the like. The liquid crystal display element includes: an electrode group formed on one or both of a pair of substrates arranged oppositely; a plurality of active elements connected to the electrode group; a liquid crystal alignment film formed on a pair of The opposite surfaces of the substrates; and a liquid crystal composition sandwiched between a pair of substrates, wherein the liquid crystal aligning film contains a polymer derived from a polyamic acid having a photodecomposable group, and the liquid crystal composition contains a polymer selected from the group consisting of: At least one compound in the group of compounds represented by formula (1). R 1 is an alkyl group with 1 to 12 carbon atoms, etc.; Ring A is 1,4-cyclohexylene, 1,4-phenylene, etc.; Z 1 is a single bond, etc.; X 1 and X 2 are hydrogen or fluorine; Y 1 is fluorine, etc.; a is 1, 2, 3 or 4. |
