Abstract

An optical compensation structure and its fabricating process are disclosed. The optical compensation structure comprises an upper polarizer film, a transparent substrate, a first retarder film (C+ plate), and a second retarder film (A-plate). The upper polarizer film provides polarization function and possesses a top surface and a bottom surface. The transparent substrate is directly laminated onto the top surface of upper polarizer film. The first retarder film is coated with a bonding layer made of crosslinking agent on one side and the bonding layer is directly laminated onto the bottom surface of upper polarizer film. The second retarder film binds to the side of first retarder film away from the upper polarizer film. The optical compensation structure is coated with the bonding layer to address the drawback of prior art where the upper polarizer film and the first retarder film are not closely adhered to each other, thereby allowing the use of one less substrate and offering a thinner compensation structure. When applied to liquid crystal display (LCD), the optical compensation structure improves the contrast and color shift problems of LCD at oblique viewing angles.
