Abstract: An organic light-emitting display device including: a substrate; a pixel electrode on the substrate; a pixel defining film on the pixel electrode and having a first opening at least partially exposing the pixel electrode; an organic light-emitting layer on the exposed portion of the pixel electrode; a common electrode on the organic light-emitting layer and the pixel defining film; an encapsulation layer on the common electrode; a black matrix on the encapsulation layer and having a second opening overlapping the first opening; and a plurality of first sensing lines on the black matrix and surrounding the pixel electrode in a plan view to define a pixel region. At least portions of the first sensing lines defining the pixel region do not overlap the common electrode in the pixel region to reduce the common electrode's influence on the touch sensing lines and improve touch sensitivity.
