The invention provides a composite glass structure used for a liquid crystal display. A functional layer of the composite glass structure comprises a single-face anti-reflection glass layer (2), a linear polaroid (3), a first lambda phase delay piece (4) and a second lambda phase delay piece (5); one face of the linear polaroid (3) is connected with the single-face anti-reflection glass layer (2), the other face of the linear polaroid (3) is connected with the first lambda phase delay piece (4), one face of the second lambda phase delay piece (5) is attached to the upper surface of a liquid crystal panel (1), and the other face of the second lambda phase delay piece (5) is attached to the other face of the first lambda phase delay piece (4). By means of the composite glass structure used for the liquid crystal display, work links and the manufacturing procedures are reduced while the anti-reflection performance, the electromagnetic shielding performance and heating performance of the liquid crystal display are guaranteed, and meanwhile chroma mura of the liquid crystal display and other display defects are avoided.
