The present invention relates to a vertical orientation type liquid crystal orientating agent and vertical orientation type liquid crystal display element. A vertical orientation type liquid crystal oThe present invention relates to a vertical orientation type liquid crystal orientating agent and vertical orientation type liquid crystal display element. A vertical orientation type liquid crystal orientating agent having excellent vertical orientation and electrical performance, and difficult to produce image retention under short-time driving and long-time driving is provided. The vertical oririentating agent having excellent vertical orientation and electrical performance, and difficult to produce image retention under short-time driving and long-time driving is provided. The vertical orientation type liquid crystal orientating agent comprises: (A) polymer selected from at least one of polyamic acid and imide polymer, wherein the polyamic acid is prepared from diamine containing specientation type liquid crystal orientating agent comprises: (A) polymer selected from at least one of polyamic acid and imide polymer, wherein the polyamic acid is prepared from diamine containing specific diamino phenyl ether, and the specific diamino phenyl ether has a steroid skeleton; and (B) polymer selected from at least one of polyamic acid and imide polymer, wherein the polyamic acid is prepfic diamino phenyl ether, and the specific diamino phenyl ether has a steroid skeleton; and (B) polymer selected from at least one of polyamic acid and imide polymer, wherein the polyamic acid is prepared from diamine containing specific diamino benzonic ester, and the specific diamino benzonic ester has a steroid skeleton, and the content ratio of the (A) polymer is 10% to 90% by weight of the toared from diamine containing specific diamino benzonic ester, and the specific diamino benzonic ester has a steroid skeleton, and the content ratio of the (A) polymer is 10% to 90% by weight of the total amount of the (A) polymer and (B) polymer.tal amount of the (A) polymer and (B) polymer.
