主　　题：narrow band filter wide color gamut display 

摘      要：We propose a narrow-band birefringent filter and its application in wide color *** birefringent filter consists of five phase retarders and two polarizers,and it has both narrow band and high *** the experiment,we fabricate the birefringent filter using quartz phase retarders and polarizers,and apply it in serval different *** color gamuts of displays are enhanced more than 30%NTSC(National Television System Committee),and the widest color gamuts that have been obtained are 126%NTSC in liquid crystal displays and 138%NTSC in organic light-emitting ***,the deep blue light in spectrum of display can be reduced using the birefringent *** birefringent filter can be an efficient element to achieve wide color gamut display.
