Claim 6:
7. A display apparatus comprising:
a display panel, having a display area;
a plurality of antenna electrodes, disposed on the display panel and overlapping the display area;
a dummy electrode, disposed around the antenna electrodes and overlapping the display area, the dummy electrode being electrically separated from the antenna electrodes and having a plurality of dummy wire segments whose extension directions intersect each other, and the dummy wire segments having a plurality of breaks;
a plurality of feed lines, respectively electrically connected to the antenna electrodes; and
a reflection layer, disposed on a side of the antenna electrodes facing the display panel and overlapping the antenna electrodes, wherein the reflection layer is adapted to reflect an electromagnetic wave having a frequency f, and a thickness of the reflection layer is greater than, 1
