Abstract
The present invention discloses a method of splicing polarized films. The method includes steps of providing a substrate; attaching a first polarized film to the substrate; attaching a second polarized film to the substrate so that a side portion of the second polarized film is correspondingly overlapped with a side portion of the first polarized film; correspondingly cutting off the overlapped side portions of the first polarized film and the second polarized film; removing separated parts of the side portions from the first polarized film and the second polarized film; and performing a flatten treatment to the cut side portions of the first polarized film and the second polarized film. The method effectively reduces the interval between spliced polarized films so that the light leakage problem at the joint position is improved.
