Abstract
A touch screen includes a first electrode layer, an insulating layer on a first electrode layer, and a second electrode layer on the insulating layer. The first electrode layer or second electrode layer includes first sensing electrode columns and second sensing electrode columns. The first sensing columns include first sensing electrodes having sub-electrodes. The second sensing electrode columns are alternately arranged with the first sensing electrode columns and include second sensing electrode. The sub-electrodes of one of adjacent first sensing electrodes are electrically connected to sub-electrodes of another one of the adjacent first sensing electrodes, respectively.
