This disclosure includes systems which generate a video game or other virtual environment, and player characters in the video game can form relationships of various natures. A first substrate is arranged opposite to a second substrate, in which the first and second substrates include a first and a second electrode, respectively. The liquid crystalline polymer composite is useful in circuit materials, circuits, and multi-layer circuits, economical to make, and has excellent flame retardant properties. Various polymers attached to a metal wiring formed on a substrate are removed by immersing the substrate into the cleaning solution. The light receiving means is arranged to receive light from the light emitting means which has passed through the region.
