A reflection liquid crystal display is such that a transparent substrate is opposed to the first substrate with a liquid crystal layer placed therebetween, and the transparent substrate is disposed forward to the first substrate in the light-incident direction. Various surfaces may be treated including metal, glass, plastics, rubber, porcelain, ceramic, marble, granite, cement, tile, sand, silica, enameled appliances, polyurethane, polyester, polyacrylic, melaminephenolic resins, polycarbonate, siliceous, painted surfaces, wood, and the like. In some embodiments, the freshening composition includes a buffering agent providing a pH of about 6 to about 8. When it is determined that the increased count value is greater than an abnormality diagnosis criterion value, then the control unit determines that the dark-current mode of the monitoring unit is malfunctioning. rights to generate a ringing tone.
