  • Patent number: 10473987
    Abstract: A display device capable of preventing deterioration in display quality caused by ions in a liquid crystal layer particularly by taking a measure against positive and negative ions is provided. A display device includes: a display region; a peripheral region outside of the display region; a light shielding layer overlapped on the peripheral region; a voltage supply wiring provided in the peripheral region; and first and second electrodes provided in the peripheral region and connected to the voltage supply wiring. The peripheral region includes first, second, third, and fourth regions. The first electrode is provided in any region among the first to fourth regions. The second electrode is provided in a region different from the region where the first electrode is formed among these regions. A polarity of a first voltage supplied to the first electrode is different from that of a second voltage supplied to the second electrode.
