1. A light emitting display device, comprising:
a display panel having a plurality of structures that include a short detection line, a first power line and a second power line as each being an individual structure within the plurality of structures;
a short detecting circuit electrically connected to the display panel through the short detection line between the first power line and the second power line, and configured to sense a value from the display panel through the short detection line, wherein an area of the second power line is greater than an area of the first power line and the short detection line, respectively; and
a determination circuit included in the short detecting circuit, the determination circuit configured to determine whether a short occurred between the first power line and the second power line at the display panel based on the value,
wherein the short detection line is positioned over the first power line.
