Abstract
The display device includes: a first electrode disposed on a substrate in a first pixel region; a first protective pattern covering at least a portion of the first electrode; a first insulating pattern covering at least a portion of each of the first electrode and the first protective pattern; a second electrode disposed on the first insulating pattern and at least partially overlapping the first electrode; a third electrode disposed in a second pixel region spaced apart from the first pixel region; a second protective pattern covering at least a portion of the third electrode; a second insulating pattern covering at least a portion of each of the third electrode and the second protective pattern; and a fourth electrode disposed on the second insulating pattern and at least partially overlapping the third electrode. The second electrode is connected to the first electrode. The fourth electrode is connected to the third electrode.
