Input detection unit and display device including the same

Abstract

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.

What is claimed is: 
     
         1 . An input detection unit comprising:
 a substrate including a detection area and a non-detection area adjacent to the detection area;   a plurality of first electrodes overlapping the detection area which extend in a first direction and are arranged successively in a second direction that intersects the first direction, wherein each of the first electrodes includes a plurality of first connection patterns and a plurality of first detection patterns connected through the first connection patterns;   a plurality of second electrodes overlapping the detection area, which are insulated from the first electrodes, extend in the second direction and are arranged successively along the first direction, wherein each of the second electrodes includes a plurality of second connection patterns and a plurality of second detection patterns connected through the second connection patterns;   dummy patterns overlapping the detection area and disposed between the first detection patterns and the second detection patterns in the detection area, the dummy patterns being either grounded or floated;   a secondary dummy pattern disposed adjacent to the dummy patterns, the secondary dummy pattern being either grounded or floated; and   signal lines overlapping the non-detection area,   wherein the signal lines include a first signal line connected to the first detection patterns and a second signal line connected to the second detection patterns,   wherein the plurality of first detection patterns includes a row of first detection patterns closest to the non-detection area, and   wherein the secondary dummy pattern overlaps a portion between the row of first detection patterns closest to the non-detection area and the second signal line, and   wherein the secondary dummy pattern is closer to the second signal line than the row of first detection patterns.
