Abstract: A display apparatus including an organic light-emitting display panel and a touch sensing unit disposed on the organic light-emitting display panel is disclosed. The touch sensing unit includes a touch electrode and a wiring part connected to the touch electrode. The wiring part of the touch sensing unit passes a protruding member disposed on a non-display region of the organic light-emitting display panel, and forms a first wiring part which does not overlap the protruding member, a second wiring part overlapping the protruding part, and a connection wiring part disposed between the first and second wiring parts and having a wiring width less than the first and second wiring parts so as to overlap an edge of the protruding member.

Abstract: Provided is an organic light emitting display module including an active area, a pad area, and a boundary area between the active area and the pad area. Unlike the active area and the pad area, since the boundary area does not include an inorganic layer, less stress is applied to the boundary area when the boundary area is bent. Display panel pads and touch sensing member pads are disposed at the same height without having a height difference therebetween. Thus, a dummy pad may be added to remove the height difference between the display panel pads and the touch sensing member pads.

Abstract: A display panel includes: first and second pixel circuits on a substrate; first and second pixel electrodes electrically connected to the first and second pixel circuits, respectively; a pixel defining layer having openings overlapping with the first and second pixel electrodes, respectively; a first emission layer on the first pixel electrode; a second emission layer on the second pixel electrode; an opposite electrode on the first emission layer and the second emission layer; and an anti-reflection layer on the opposite electrode. The anti-reflection layer includes: a light-blocking portion corresponding to an area between the openings of the pixel defining layer; a first color filter overlapping with the first emission layer; a second color filter overlapping with the second emission layer; and an overcoat layer including a portion located in a separation space between the light-blocking portion and at least one of the first color filter or the second color filter.
