A display apparatus includes an organic light emitting display panel including a circuit layer and a touch sensing unit disposed on the organic light emitting display panel and including sensor blocks and touch signal lines connected to the sensor blocks. The circuit layer includes first signal lines disposed on a base layer, a first insulation layer disposed on the first signal lines, second signal lines disposed on the first insulation layer, and dummy conductive patterns. Each of the touch signal lines includes a touch line part and a touch pad part connected to an end of the touch line part. The dummy conductive patterns include a dummy conductive pad disposed directly on a same layer as the first signal lines or the second signal lines and overlap the touch pad part.
