Abstract
A liquid crystal display device includes a pair of first and second transparent substrates having first and second transparent conductive films formed on opposing surfaces, with liquid crystal between the first and second transparent substrates. An airtight seal encapsulates the liquid crystal, and includes a conducting portion which electrically interconnects the transparent conductive films. The transparent conducive films have metal thin films deposited on respective surface portions, including the conducting portion. A driving circuit is connected to the metal thin films, to control the liquid crystal. Spacer members are mixed and generally evenly dispersed in the seal, for controlling the thickness of the seal, which comprises first spacer members mixed in the conducting portion, and second spacer members mixed in portions of the seal other than the conducting portion. The first spacer members have a particle diameter smaller than that of the second spacer members by a predetermined value X.
