## Abstract

A plasma display apparatus comprising a connector is provided. The plasma display apparatus comprises a plasma display panel comprising an electrode of a predetermined width and a connector comprising an electrode line of a width narrower than the predetermined width of the electrode to supply a driving signal to the electrode. A distance between the electrode line and an adjacent electrode line is longer than a distance between the electrode and an adjacent electrode.

## Claims

### Claim 1

A plasma display apparatus comprising:
a plasma display panel including an electrode;
a connector including an electrode line configured to supply a driving pulse to the electrode, the electrode line exhibiting a quadrilateral-shaped cross-section, with a width of a first side of the electrode line that contacts the connector and a width of a parallel second side of the electrode line nearest to the electrode each being less than a width of the electrode; and
a conductive adhesive film layer formed between the electrode and the electrode line,
wherein:
in an area where the electrode line and the electrode overlap, a distance between the electrode line and an adjacent electrode line is greater than a distance between the electrode and an adjacent electrode,
a distance between the parallel second side of the electrode line and the parallel second side of the adjacent electrode line is greater than a distance between the first side of the electrode line and the first side of the adjacent electrode line, and
the distance between the first side of the electrode line and the first side of the adjacent electrode line is greater than the distance between the electrode and the adjacent electrode.

### Claim 2 (depends on 1)
