1. A display device comprising:
a first substrate in which a plurality of pixel areas is defined;
a plurality of pixels including a plurality of light emitting layers between a plurality of lower electrodes and an upper electrode on the first substrate;
a second substrate on the light emitting layers, wherein the second substrate has a side facing the first substrate, wherein the light emitting layers are disposed between the second substrate and the first substrate;
touch sensing patterns on the side of the second substrate and including touch sensing electrodes, wherein the touch sensing patterns are between the first substrate and the second substrate;
dummy patterns between the touch sensing patterns; and
a plurality of connecting lines connected to the touch sensing patterns,
wherein the touch sensing patterns and the connecting lines are formed of metal,
wherein the touch sensing patterns and the connecting lines are on a same layer,
wherein each of the touch sensing patterns is connected to the connecting lines,
wherein the touch sensing electrodes of the touch sensing patterns have a reflectivity by which the touch sensing electrodes perform a mirror function, and
wherein a length of a planar shape of at least one of the dummy patterns is same as a length of a planar shape of a touch sensing electrode member of the touch sensing electrodes in a first direction crossing a second direction in which the dummy patterns and the touch sensing electrode member is arranged, and
wherein a length of the planar shape of the at least one of the dummy patterns is same as a length of a planar shape of a touch sensing electrode member of the touch sensing electrodes in the second direction.
