Abstract:
In a liquid crystal display device including a first transparent substrate having a first transparent conductive film formed on a surface thereof, a second transparent substrate having a second transparent conductive film formed on a surface thereof opposed to said first transparent conductive film, liquid crystal sandwiched between said first transparent substrate and said second transparent substrate, a seal encapsulating said liquid crystal in an airtight manner, and a driving circuit, said seal including a conducting portion disposed so as to electrically interconnect said first transparent conductive film and said second transparent conductive film, said first and second transparent conductive films having metal thin films deposited on respective predetermined surface portions thereof including said conducting portion, said driving circuit being connected to said metal in films for carrying out liquid crystal display control,the improvement comprising: a plurality of spacer members mixed and generally evenly dispersed in said seal, for controlling thickness of said seal, said plurality of spacer members comprising first spacer members mixed in said conducting portion, and second spacer members mixed in portions of said seal other than said conducting portion, said first spacer members having a particle diameter smaller than that of said second spacer members by a predetermined value X; and a multiplicity of conductive members mixed in said conducting portion; wherein said metal thin films have a multiplicity of protrusions formed thereon; and wherein said first and second transparent conductive films are electrically interconnected via said conductive members and said protrusions.
