Zusammenfassung:	The present invention relates to a colour purity improvement film (a color gamut enhancing 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 as liquid crystal display device.
