Provided is an input detection unit with a plurality of first electrodes and second electrodes insulated from the first electrodes. Dummy patterns are disposed between the patterns and the detection patterns. A secondary dummy pattern is disposed adjacent to the dummy patterns. Signal lines overlap the non-detection area. The signal lines include a first signal line connected to the patterns and a second signal line connected to the detection patterns. The plurality of patterns includes a row of patterns closest to the non-detection area. The secondary dummy pattern overlaps a portion between the row of patterns closest to the non-detection area and the second signal line.
