Abstract
A display device includes a base layer including an upper base layer and a lower base layer on a rear surface of the upper base layer; at least one light emitting element on a surface of the upper base layer; and at least one pad on the rear surface of the upper base layer and including a first pad layer adjacent to the upper base layer and a second pad layer adjacent to the lower base layer. The second pad layer includes indium zinc oxide (IZO).
