Abstract

The disclosure discloses a liquid crystal display, a liquid crystal display panel and a manufacture method thereof. The manufacture method includes producing a first auxiliary base and a second auxiliary base respectively, aligning and assembling the first auxiliary base and the second auxiliary base to form a liquid crystal cell, attaching reinforcement bases on a top surface and a bottom surface of the liquid crystal cell. A total thickness of the first auxiliary base and the second auxiliary base is D, a total thickness of a first standard auxiliary base and a second standard auxiliary of a standard liquid crystal display panel met a minimum structural strength requirement is defined as d, D is less than d. Which can reduce the thickness of the liquid crystal display panel to achieve an ultrathin structure of the liquid crystal display panel.
