Abstract: A liquid crystal display device includes a thin film transistor (TFT) substrate and a counter substrate that are disposed opposite to each other with a liquid crystal layer in between. The TFT substrate has, an organic passivation film formed covering the TFT, and a pixel electrode and a common electrode formed on the organic passivation film, the organic passivation film having a through-hole to connect the pixel electrode and the TFT. A columnar spacer is formed on the counter substrate to define a distance between the TFT substrate and the counter substrate. A planarization film made of resin is formed in the through-hole. A recess is formed in the through-hole by a surface of the planarization film and a sidewall of the through-hole. A tip end of the columnar spacer exists in the recess.

Abstract: In a plan view, a spacer member is arranged at a position overlapping with a first line portion of a second pixel electrode. The second pixel electrode has a second connecting portion that connects the first line portion and the second line portion arranged next to the first line portion. The second connecting portion of the pixel electrode is arranged between a region where the first line portion of the second pixel electrode overlaps with the spacer member and one end portion of the first line portion of the second pixel electrode.

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.
