Abstract:
A plasma addressed liquid crystal display device, comprising:a plasma cell substrate;a counter substrate;a liquid crystal layer interposed between the plasma cell substrate and the counter substrate,the plasma cell substrate including a first substrate, a dielectric sheet provided on a side of the liquid crystal later, and a plurality of stripe-shaped discharge channels surrounded by a plurality of partition walls formed in a gap between the first substrate and the dielectric sheet,the counter substrate including a second substrate, and a plurality of stripe-shaped electrodes formed on the second substrate so as to extend perpendicularly to the plurality of stripe-shaped discharge channels,wherein each of intersection regions of the plurality of discharge channels and the plurality of stripe-shaped electrodes defines a picture-element region,wherein the dielectric sheet includes a sheet-like dielectric, a plurality of conductive portions extending between surfaces of the sheet-like dielectric which respectively face the discharge channels and the liquid crystal layer, and a plurality of first conductive layers formed on a surface of the dielectric sheet which faces the discharge channels, each of the plurality of first conductive layers being electrically connected to at least one of the plurality of conductive portions; andwherein each of the plurality of first conductive layers is at least partially located in a central area of a corresponding discharge channel.
