LIQUID CRYSTAL DISPLAY DEVICE, POLARIZING PLATE, AND POLARIZER PROTECTIVE FILM |
摘要 |
The purpose of the present invention is to further suppress the occurrence of spectral irregularities in a liquid crystal display device that uses a light emitting diode as a light source, and uses an oriented polyester film having a given retardation as a polarizer protective film. This liquid crystal display device includes a backlight light source, two polarizing plates, and a liquid crystal cell disposed between the two polarizing plates. The backlight light source is a white light source having a continuous emission spectrum. The two polarizing plates are each formed from a polarizer and protective films on both sides of the polarizer. At least one of the protective films on either side is an oriented polyester film having a retardation of 3000 to 30000 nm. The main orientation axes of the oriented polyester films configuring the two polarizing plates are substantially parallel to each other. |
