Large-scale display device

A display device comprising:

• a plurality of display modules each of which include a plurality of plasma tubes extending in a column direction and arranged in a row direction parallel to each other, a plurality of pairs of display electrodes extending parallel to each other perpendicularly to the plasma tubes, and a plurality of address electrodes extending parallel to each other along the plasma tubes;
• wherein the display modules are arranged in a matrix and are supported by a support member so that the display modules aligned in the row direction of the matrix adjoin each other with no step therebetween and the display modules aligned in the column direction of the matrix adjoin each other with a step therebetween,
• wherein each plasma tube includes a first end which has a first non-display region, a second end which has a second non-display region, and a third non-display region between adjacent two pair of display electrodes,
• wherein a length Da1 of the first non-display region, a length Da2 of the second non-display region, and a length D of the third non-display region are defined as follows;
• Da1≈Da2<D
• wherein the adjoined display modules in the column direction overlap each other to respectively have overlap portions and the first ends of the plasma tubes of a display module overlap the second ends of the plasma tubes of another adjacent display unit.
