<P>PROBLEM TO BE SOLVED: To provide a composite polarizing plate excellent in visibility under bright environment, capable of reducing parallax and capable of reducing thickness of the liquid crystal display device, and to provide a liquid crystal display device. <P>SOLUTION: The composite polarizing plate is used in the liquid crystal display device including a liquid crystal cell, a front substrate, and a parallel light source device and has a polarizer and a light diffusion adhesive layer arranged on one side of the polarizer. The composite polarizing plate is arranged to bring the light diffusion adhesive layer into contact with the front substrate for use in the liquid crystal display device. Since the front substrate can be joined with the light diffusion adhesive layer by using this composite polarizing plate, an air layer is not formed between the polarizer and the front substrate. Consequently, this composite polarizing plate achieves excellent visibility under bright environment, reduces palallax, makes the liquid crystal display device thin, and significantly improves the effect of improvement of front contrast ratio by the parallel light source device. <P>COPYRIGHT: (C)2011,JPO&INPIT |
