More Information
Summary:Provided is an optical member with an excellent color viewing angle and an excellent color reproduction range. The optical member comprises: a narrowband reflection polarized part; and a broadband reflection polarized part laminated on the narrowband reflection polarized part, wherein the width of a reflection polarized wave band of the narrowband reflection polarized part is smaller than the width of the reflection polarized wave band of the broadband reflection polarized part, and a reflection wavelength center wavelength of the narrowband reflection polarized part is placed in a wavelength band equal to or greater than a red wavelength. 광학 부재가 제공된다. 광학 부재는 협대역 반사편광부, 및 협대역 반사편광부 상에 적층된 광대역 반사편광부를 포함하되, 협대역 반사편광부의 반사편광 파장대역의 폭은 광대역 반사편광부의 반사편광 파장대역의 폭보다 작으며, 협대역 반사편광부의 반사파장 중심파장은 적색 파장보다 크거나 같은 파장 대역에 위치한다.
