Conventional touch pattern electrodes can be arranged in a lattice. The light emitted from the light source may cause coherence due to the gap between the touch pattern electrodes and the bridge pattern connecting the touch pattern electrodes. When the pixel emits light due to the coherence phenomenon, a visibility problem may occur due to a problem of light mixing at the interface of the bridge electrode.
