Abstract

The invention discloses a high-transmittance low-reflection electromagnetic screening structure for a liquid crystal display screen and a manufacturing method for the structure. The structure is characterized by sequentially consisting of a first polarizer layer (2), a first quarter wavelength delaying layer (3), a transparent indium tin oxide conductive layer (4), a second quarter wavelength delaying layer (5), a second polarizer layer (6) and a reflection reducing layer (7) which serve as optical functional layers, wherein the optical functional layers are connected with one another to form a whole body by using transparent optical cement (8) by a binding process; and the first polarizer layer (2) is closely adjacent to the liquid crystal display screen (1). The manufacturing method comprises the following steps of: optically binding the optical functional layers in sequence by using the optical cement and solidifying for shaping. The structure has the advantages of high transmittance and relatively low electromagnetic reflectivity, the advantages of the conventional electromagnetic screening technology and a good effect, and is low in cost.
