PROBLEM TO BE SOLVED: To provide a display device capable of preventing degradation in display quality by ions in a liquid crystal layer.SOLUTION: A display device relating to one embodiment includes a first substrate, a second substrate opposing to the first substrate, and a liquid crystal layer present between the first substrate and the second substrate. The display device further includes a display region, a peripheral region outside the display region, a light-shielding layer overlapping the peripheral region, a voltage supply wiring disposed in the peripheral region and extending in a first direction, and a first electrode and a second electrode disposed in the peripheral region and connected to the voltage supply wiring. The first electrode and the second electrode are alternately arranged in the first direction or a second direction; and a first voltage supplied to the first electrode is different from a second voltage supplied to the second electrode.SELECTED DRAWING: Figure 3 【課題】 液晶層中のイオンによる表示品位の低下を防止可能な表示装置を提供する。【解決手段】 一実施形態に係る表示装置は、第１基板と、上記第１基板に対向する第２基板と、上記第１基板及び第２基板の間にある液晶層と、を備える。さらに、上記表示装置は、表示領域と、上記表示領域の外側の周辺領域と、上記周辺領域と重畳する遮光層と、上記周辺領域に設けられ、第１方向に延在する電圧供給配線と、上記周辺領域に設けられ、上記電圧供給配線に接続された第１電極及び第２電極と、備える。上記第１電極及び上記第２電極は、上記第１方向又は第２方向において交互に配列している。そして、上記第１電極に供給される第１電圧と、上記第２電極に供給される第２電圧とが異なる。【選択図】 図３
