Title:
LIQUID CRYSTAL DISPLAY DEVICE AND POLARIZING PLATE
Document Type and Number:
WIPO Patent Application WO/2017/065148
Kind Code:
A1
Abstract:
This liquid crystal display device is provided with a backlight light source, two polarizing plates, and a liquid crystal cell arranged between the two polarizing plates. The backlight light source is a white light emitting diode having an emission spectrum that has peak tops in wavelength ranges from 400 nm (inclusive) to 495 nm (exclusive), from 495 nm (inclusive) to 600 nm (exclusive), and from 600 nm (inclusive) to 780 nm (inclusive), while having a half-value width of less than 5 nm for a peak that has the highest peak intensity within the wavelength range from 600 nm (inclusive) to 780 nm (inclusive). At least one of the polarizing plates is obtained by laminating a polyester film on at least one surface of a polarizer; the polyester film has a retardation of 1,500-30,000 nm; and an anti-reflection layer and/or a low reflection layer are laminated on at least one surface of the polyester film.
