Abstract:
A reflective display comprising:a panel having a transparent first substrate located on the incident side of outside light, a second substrate bonded to said first substrate with interposition of a prescribed space and located on the side opposite to said first substrate, an electro-optical substance held in said space, and an electrode for applying a voltage to said electro-optical substance formed at least on any one of said first substrate and said second substrate;a lighting apparatus having a transparent light guide plate placed on the outside of said first substrate, and a light source provided on the end of said light guide plate for emitting the illumination light as required,wherein said light guide plate normally allows the outside light to be transmitted, which is incident on said first substrate, and allows the outside light reflected on said second substrate to come out, on the other hand, said light guide plate guides the illumination light as required, which is incident on said first substrate, and allows the illumination light reflected on said second substrate to come out;a polarization plate; anda quarter wavelength plate,wherein a lamination structure of said polarization plate and said quarter wavelength plate are attached on said light guide plate one on the other, and the outside light or the illumination light reflected unnecessarily on the first substrate of said panel is shut off.
