LENS UNIT AND LAMINATED FILM

Abstract: a lens unit including: a reflection-type polarizing member configured to reflect light; a first lens portion arranged on an optical path between the display element and the reflection-type polarizing member; a half mirror arranged between the display element and the first lens portion; a second lens portion arranged the a front side of the reflection-type polarizing member; a second �/4 member arranged on an optical path between the half mirror and the reflection-type polarizing member; and a first protective member and a second protective member each arranged on the optical path between the half mirror and the reflection-type polarizing member. the first and second protective members are arranged to face each other through a space, and the first and second protective members each have a maximum value for a 5� specular reflectance spectrum in a wavelength range of from 420 nm to 680 nm of 1.2% or less.
