| description | A display unit of the present invention includes a display section (10) that outputs a first linearly-polarized light as image light, and a display switching section (20) that performs switching between an image display mode and an external light reflection mode. The display section (10) includes a first absorption-type polarization member (11) that allows the first linearly-polarized light to pass through and absorbs second linearly-polarized light. The display switching section (20) includes a reflection-type polarization member (21), a switchable transmission polarization axis member (22), and a second absorption-type polarization member (23). The reflection-type polarization member (21) allows the first linearly-polarized light to pass through and reflects the second linearly-polarized light. The switchable transmission polarization axis member (22) performs switching between a first mode in which the first linearly-polarized light is converted into the second linearly-polarized light and a second mode in which the first linearly-polarized light is not converted into the second linearly-polarized light. The second absorption-type polarization member (23) allows the first linearly-polarized light to pass through and absorbs the second linearly-polarized light. The second absorption-type polarization member (23) has a hue b* value that is equal to or smaller than a hue b* value of the first absorption-type polarization member (11). |
