Abstract
A plasma display panel that is capable of improving a contrast as well as reducing the power consumption. In the plasma display panel, a distance between the sustaining electrode pair at a display region is different from that a non-display region. A width of the barrier rib at the display region is different from that at the non-display region. The non-display region is provided with black matrices for shutting off a light. A protective layer is provided only at the display region.
Claims54
A plasma display panel comprising:
- a plurality of cells;
- and
- a plurality of barrier ribs in a first direction, each barrier rib being formed between adjacent cells of the first direction;
- and
- wherein fluorescent material is provided for a display area and a non-display area is provided adjacent to the display area,
- wherein a width of at least one of the barrier ribs at a boundary of the display area and non-display area is different from a width of at least one of the barrier ribs in the display area, and
- wherein cells provided in the display area and provided adjacent to the at least one of the barrier ribs at the boundary of the display area and non-display area include fluorescent material such that a side of the at least one of the barrier ribs at the boundary of the display area and non-display area is provided with the fluorescent material.

A plasma display panel comprising:
- a plurality of cells;
- and
- a plurality of barrier ribs, each barrier rib being formed between adjacent cells which are in the same direction as the barrier rib,
- wherein light emission is allowed for a display area, and light emission is prohibited for a non-display area, and
- wherein a width of at least one of the barrier ribs at a boundary of the display area and the non-display area is different from at least one of the barrier ribs in the display area, and
- wherein cells provided in the display area and provided adjacent to the at least one of the barrier ribs at the boundary of the display area and non-display area are configured to emit light.
