Abstract: A liquid crystal display panel includes a plurality of pixels. The pixels each include a pixel electrode, a common electrode, and a liquid crystal that rotates in-plane due to voltage applied by the pixel electrode and the common electrode. The pixel electrode includes a linear electrode. When an initial alignment direction of the liquid crystal for which dielectric anisotropy is positive, or a direction perpendicular to the initial alignment direction of the liquid crystal for which dielectric anisotropy is negative is defined as a predetermined first direction, at a boundary between pixels, of the plurality of pixels, that are adjacent to each other, a boundary line between the adjacent pixels, the linear electrode, and an end side of the linear electrode are inclined with respect to the predetermined first direction, and inclining directions with respect to the predetermined first direction of the boundary line, the linear electrode, and the end side are identical.

Abstract: A liquid crystal display device includes a first liquid crystal display panel in which a first main pixel including subpixels is arranged in a matrix, and that displays a color image, and a second liquid crystal display panel that includes a second main pixel corresponding to a plurality of the first main pixel, and that displays a monochrome image. The second main pixel is divided into a plurality of regions, and has pixel electrodes disposed in the plurality of regions and a plurality of light shields. At least a portion of the plurality of light shields is formed from a switching element that connects to each of the pixel electrodes, and the plurality of light shields is arranged in a staggered manner. The light shields positioned within one set of the regions formed from adjacent regions forms one set of the light shields.

Abstract: A liquid crystal display device includes a first liquid crystal display panel, and a second liquid crystal display panel that overlaps the first liquid crystal display panel. At least one of the first liquid crystal display panel and the second liquid crystal display panel includes a light blocking pattern that is repeatedly arranged and has light blocking properties. The light blocking pattern includes a first light blocking line and a second light blocking line that extend in a predetermined direction. The first light blocking line includes a first incline inclined with respect to the predetermined direction, and a second incline inclined in a direction opposite the first incline with respect to the predetermined direction, and the second light blocking line is adjacent to the first light blocking line and is line-symmetrical, with respect to the predetermined direction, to the first light blocking line. At least one of the first light blocking line and the second light blocking line is formed from one of scan wirings and signal wiring of the first liquid crystal display panel and the second liquid crystal display panel.
