A reflective display device includes a panel, a light guide plate and a light source. The panel is provided with a transparent first substrate lying on the side of the external incident light, a second substrate joined to the first substrate with a predetermined gap therebetween and lying on the reflection side, a guest-host liquid crystal layer held in the gap between the substrates, and electrodes provided on each substrate for applying a voltage to the guest-host liquid crystal layer. The light guide plate is composed of a transparent material and is arranged on the outside of the first substrate. The light source is arranged on the end of the light guide plate and generates illumination light as required. The light guide plate normally transmits external light onto the first substrate and emits the external light reflected from the second substrate, and also, as required, guides illumination light onto the first substrate and emits the illumination light reflected from the second substrate.
