PURPOSE:To display plural independent pieces of picture information on a single panel by sandwiching discharge space of fluorescent substance elements with two substrates, separating it with barriers and forming fluorescent substance elements only on specific planes. CONSTITUTION:In the case where information is displayed by excitation luminescence of fluorescent substance elements L, in each discharge cell, fluorescent substance elements L are formed only on specific planes of barriers D. By forming fluorescent substance elements L only on one side face of the wall D partitioning a discharge cell, the lighting is confirmed only when viewed in this direction. Thus, visible light due to fluorescent substance elements is emitted only in direction, so that the lighting is confirmed only when viewed in this direction. Accordingly, by changing the walls formed with fluorescent substance elements in respective discharge cells Sij, plural independent pieces of picture information are displayed on a single panel. |
