COLOUR PURITY IMPROVEMENT FILM FOR LIQUID CRYSTAL DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE HAVING SAME

摘要

The present invention relates to a colour purity improvement film that can improve the colour purity of a liquid crystal display device, and a liquid crystal display device having the same. According to the present invention, a liquid crystal display device that blocks unnecessary wavelengths other than RGB wavelengths so as to improve colour gamut and colour purity may be provided by introducing a combination of dyes that absorb a particular wavelength band to the inside of an adhesion layer or a coating layer of a liquid crystal display device.
