Provided is a liquid crystal display assembly, comprising a first substrate (11), a second substrate (12), and a liquid crystal layer (30). A first device unit (110) is provided on a lower surface of the first substrate (11), and a second device unit (120) is provided on an upper surface of the second substrate (12), so that a plurality of first device units (110) and a plurality of second device units (120) are opposite one another, and a first thin film transistor (111) and a second thin film transistor (121) are overlapped in a direction perpendicular to the first substrate (11) and the second substrate (12).
