Abstract: A light emitting display device includes a display panel, a structure for short detection, and a short detecting unit. The display panel displays an image. The structure for short detection includes a first power line, a second power line, and a short detection line disposed between the first power line and the second power line in the display panel. The short detecting unit senses a sensing value from the short detection line and determines whether a short occurs in the display panel on the basis of the sensing value.
