A liquid crystal display (LCD) cell is provided having transparent plates that are substantially parallel to each other and contain a liquid crystal display material. A plurality of spacers are interposed between the transparent plates to define a distance between the plates. At least one of the spacers exhibits dimensions and properties different than another of the spacers. The different dimensions and properties operate to control the distance at various temperatures to prevent non-uniform color effects and vacuum void formations.
