    • A high-definition liquid crystal display device is provided. A liquid crystal display device with a high aperture ratio is provided. A liquid crystal display device with a high contrast ratio and display quality is provided. A liquid crystal display device capable of being driven at a low voltage is provided. The display device includes, between a pair of substrates, a pixel electrode, a first common electrode, a second common electrode, and a liquid crystal layer. The pixel electrode and the first common electrode are positioned between the liquid crystal layer and one of the substrates. The second common electrode is positioned between the liquid crystal layer and the other substrate. The same potential is supplied to the first common electrode and the second common electrode. The first common electrode includes a portion overlapping with the second common electrode between the display regions of two adjacent subpixels that exhibit different colors. At least one of the pixel electrode and the first common electrode includes a portion that does not overlap with the second common electrode in the display region of the subpixel.
    • 提供了一种高分辨率液晶显示装置。 提供了具有高开口率的液晶显示装置。 提供了具有高对比度和显示质量的液晶显示装置。 提供了一种能够以低电压驱动的液晶显示装置。 显示装置在一对基板之间包括像素电极,第一公共电极,第二公共电极和液晶层。 像素电极和第一公共电极位于液晶层和一个基板之间。 第二公共电极位于液晶层和另一基板之间。 向第一公共电极和第二公共电极提供相同的电位。 第一公共电极包括与显示不同颜色的两个相邻子像素的显示区域之间的第二公共电极重叠的部分。 像素电极和第一公共电极中的至少一个包括在子像素的显示区域中与第二公共电极不重叠的部分。
