Abstract: A display device includes a first light shielding part provided between a filter film and a first electrode, and a second light shielding part provided on a second substrate. First and second filter films each have long sides that extend in a first direction in which a video signal line extends, and the first and the second filter films are arranged adjacent to each other in a second direction different from the first direction. The first light shielding part overlaps the video signal line in a plan view. The second light shielding part overlaps a metal electrode in the plan view.

Abstract: According to one embodiment, a liquid crystal display device includes an array substrate, a counter substrate, a liquid crystal layer and a driving unit. The driving unit is configured to perform polarity inversion driving by applying, to the pixel electrode, positive and negative video signals. When applying the video signals to the pixel electrode, the driving unit superposes a correction signal corresponding to a polarity inversion frequency and the gray level on the video signals in advance.

Abstract: According to one embodiment, a liquid crystal display device includes a first substrate, a second substrate and a liquid crystal layer. The first substrate includes a first electrode, a stage including an electrode formation surface, a switching element, a second electrode and a first vertical alignment film. The second substrate includes a third electrode and a second vertical alignment film. The electrode formation surface is positioned closer to the second substrate than a portion of the first vertical alignment film, which opposes the first electrode.
