Abstract: A display device including a display function layer between first and second substrates, respectively, a black matrix having an effective display region and a frame region, a first antenna unit for touch sensing signal, a second antenna unit for power signal, first and second conductive lines perpendicularly to one another, first active elements formed in the frame region, a third antenna unit for touch sensing signal, a fourth antenna unit for power signal, second active elements for driving the display function layer, and third and fourth conductive lines formed perpendicularly to one another. In a plan view from the first substrate toward the second substrate, the first and third antenna units overlap for transmitting or receiving a touch sensing signal, with a positional accuracy within ±3 μm, and the second and fourth antenna units overlap for receiving a power signal, with a positional accuracy within ±3 μm.
