Abstract: A curved liquid crystal display includes a first panel having a pixel electrode including crossed stem parts, a plurality of fine branch parts extending from the crossed stem parts, and fine slits positioned between fine branch parts adjacent to each other, a second panel having a common electrode, and a liquid crystal layer between the first panel and the second panel. Misalignment between the first panel and the second lower panel is determined and a pitch, which is a sum of a width of the fine branch part and a width of the fine slit, gradually increases from a region having a small misalignment toward a region having a large misalignment.

Abstract: A liquid crystal display device includes a display panel including: a lower display substrate on which a plurality of pixel electrodes are disposed in a matrix and data lines extend in a column direction between adjacent pixel electrodes; an upper display substrate on which a common electrode is disposed; and a liquid crystal layer disposed between the lower display substrate and the upper display substrate and including liquid crystal molecules. The display panel includes a plurality of unit pixels, each unit pixel including pixels having different colors, and each pixel including one of the pixel electrodes. A gap between neighboring unit pixels is larger than a gap between neighboring pixel electrodes within each unit pixel, and a data line positioned between the neighboring unit pixels has a portion having a width larger than that of a data line positioned between the neighboring pixel electrodes within each unit pixel.
