Filed: 1989-08-28
Abstract: PURPOSE:To decrease the probability that a longitudinal electrode is covered by a barrier, even with an increase in the barrier width caused by dislocation of the barrier or paste drop, etc., or decrease in the width of the longitudinal electrode, etc., so as to prevent lack of picture elements that may arise from stoppage of electric discharge by adopting such configuration that adjacent picture elements bite into one another. CONSTITUTION:The arrangement and configuration of picture elements is stretched to the side of line electrodes 3 more than conventional ones and the picture elements are so arranged as to bite into one another. As to one side of a triangle connecting the centers of the picture elements 11 which side is parallel to longitudinal electrodes 4 and the distance x from the crossing point of a barrier 9 to the center, the distance (x) is half the distance (z) from the parallel side to the apex of the triangle within normal arrangement of rectangular picture elements. When the configuration of the picture elements 11 is such that they bite into one another to the side of the longitudinal electrode 4, then the distance (x) is less than half the distance (z) and in extreme cases the distance (x) is zero; the probability that the longitudinal electrodes are covered by the barrier due to slight dislocation of the barrier, broadening of the barrier width or narrowing of the width of each longitudinal electrode is therefore decreased and electric discharge is stably maintained.
