Abstract
A display device includes a substrate. The substrate includes a substratum. The substratum includes a main touch control area which includes a plurality of first touch control electrodes and a plurality of second touch control electrodes that are insulated from each other and intersect with each other. A first dummy electrode is disposed between the adjacent first touch control electrodes, and is electrically connected to the first touch control electrodes which are adjacent to the first dummy electrode. A second dummy electrode is disposed between the adjacent second touch control electrodes, and is electrically connected to the second touch control electrodes which are adjacent to the second dummy electrode. The material of the first dummy electrode and the second dummy electrode is photosensitive resistive material that is sensitive to light of a specific wavelength band, and both the first dummy electrode and the second dummy electrode are transparent.
