A liquid crystal display assembly and an electronic device are provided. The liquid crystal display assembly includes: a touch screen, an upper substrate in parallel to the touch screen, a lower substrate in parallel to the upper substrate, a liquid crystal layer embedded between the upper and lower substrates, an upper polarizing plate and a lower polarizing plate attached to one side of the upper substrate and one side of the lower substrate which are opposite to the liquid crystal layer, respectively, and at least one fingerprint recognition sensor, at least one optical proximity sensor and a control chip. The at least one fingerprint recognition sensor and the at least one optical proximity sensor are respectively disposed between the upper polarizing plate and the lower polarizing plate, and the fingerprint recognition sensor is electrically connected to the control chip.
