ABSTRACT:
A plasma address liquid crystal display device having a flat panel structure which is composed of display cells and plasma cells bonded to one another with an intermediate sheet, and in which position registration tolerance between the display and plasma cells can be made less strict. A plasma cell 2 has discharge channels 5 extending in the row direction. The display cell 1 has a electro-optical device 9 and signal electrodes 10 extending along the column direction. Pixels 11 are defined at the points of intersections of the signal electrodes 10 and the discharge channels 5. The electro-optical device 9 is a set of finely partitioned liquid crystal areas 15 and is controlled in orientation to axis-symmetrical orientation. The liquid crystal areas 15 are continuously arrayed at a constant pitch DP finer than an arraying pitch CP of the pixels 11 at least in the column direction. This structure can be extensively applied to the active matrix type liquid crystal display device.
