Abstract: According to one embodiment, a display device includes a switching element, a common electrode, an insulating film covering the common electrode, a first pixel electrode electrically connected to the switching element in a first contact hole penetrating the insulating film, and a transparent conductive film electrically connected to the common electrode in a second contact hole penetrating the insulating film. The first pixel electrode and the transparent conductive film are arranged in a first direction in a same layer. A size of the first contact hole and a size of the second contact hole are different from each other in planar view.

Abstract: A liquid crystal display device includes a first substrate, a second substrate, a liquid crystal sandwiched between the substrates, and a display region. A hole portion is formed in the display region. A first seal portion is formed to surround the display region. A second seal portion is formed to surround the hole portion. The first and the second seal portions seal the liquid crystal. The second seal portion has a first end portion on the liquid crystal side and a second end portion on the opposite side of the liquid crystal side. A sealing material is present in the first end portion. A sealing material is present in the second end portion. A wall-like spacer is formed between the first and the second end portions to surround the hole portion. The wall-like spacer defines the gap between the first and the second substrates.

Abstract: According to one embodiment, a liquid crystal display device comprises first and second substrates, a sealing member, and a liquid crystal layer. The first substrate includes an image display area, a peripheral area, a common electrode, a scanning line, a signal line, a switching element, a pixel electrode, and first and second electrodes. At least a part of the first electrode is formed of a metal material and is closer to the liquid crystal layer than the scanning and signal lines. The first voltage is applied to the first electrode and the second voltage is applied to the second electrode. Ions in the liquid crystal layer are trapped by an electric field formed between the first and second electrodes.
