Abstract
To provide a plasma addressed liquid crystal display device which can enhance the bonding strength between the dielectric sheet and the plasma substrate glass, a frit seal is provided at the outside of the barrier ribs, and dummy barrier ribs and a frit seal are sequentially provided on the outside of the frit seal. The frit seal has a greater width than that of the frit seal and has a role as a reinforcing member. The dielectric sheet and a plasma substrate glass are provided so as to sandwich the barrier ribs. A liquid crystal layer is provided on a surface side of the dielectric sheet.
Claims4
A plasma addressed liquid crystal display device, comprising:
- a liquid crystal cell including:
- a first substrate having transparent electrodes arranged in a column direction on an inner surface of said first substrate;
- an intermediate sheet adhered to the first substrate and spaced from said first substrate to define a gap between said intermediate sheet and said first substrate;
- and
- a liquid crystal layer held in the gap;
- a plasma cell including:
- a second substrate having discharge electrodes arranged in a row direction, said second substrate having an inner surface facing said intermediate sheet;
- a plurality of barrier ribs on said inner surface of said second substrate;
- an ionizable gas sealed between the second substrate and the intermediate sheet by providing a bonding means outside of the barrier ribs;
- a ring-shaped strengthening means for strengthening which is provided between the second substrate and the intermediate sheet being formed outside of the bonding means;
- and
- dummy ribs being provided between said bonding means and said strengthening means.
