Abstract
A plasma addressed liquid crystal display device is disclosed wherein the dimension of a gap of a liquid crystal cell is controlled uniformly over the entire area of the screen of the display device. The display device comprises a first substrate having a plurality of striped data electrodes formed substantially in parallel on a major surface thereof, a second substrate disposed in an opposing relationship to the first substrate and having a plurality of discharge electrodes formed thereon perpendicularly to the data electrodes, an intermediate sheet interposed between the first and second substrates and cooperating with the second substrate to define a discharge chamber between them, a plurality of barrier ribs having top surfaces for contacting in a contacting pattern with a surface of the intermediate sheet, an adhesive spacer interposed between the first substrate and the intermediate sheet and adhered to and cooperating with the other surface of the intermediate sheet to define a gap, the adhesive spacer having a pattern corresponding to the contacting pattern, and a liquid crystal layer enclosed in the gap and having a thickness determined by the adhesive spacer.
