    • Disclosed is an electrophoretic display and a method for driving the electrophoretic display. The method for driving the electrophoretic display, which includes a first electrode, a second electrode, and an electrophoretic layer including electrophoretic particles disposed in a plurality of pixels receiving the voltage for driving from the first electrode and the second electrode and provided between the first electrode and the second electrode includes applying a reset voltage to the pixels, applying a reset compensation voltage including reversed polarity to the reset voltage to the pixels, applying an image display voltage including the same or different polarity during a predetermined time between the neighboring pixels, and applying an image display compensation voltage including reversed polarity to the image display voltage to the pixels during a predetermined time. The foregoing method provides a potential distribution which is symmetrical in the boundary region between the neighboring pixels such that the display size of the real image of each of the pixels is uniform and an afterimage may be prevented, thereby improving the display performance.

    • A display substrate includes respective pluralities of gate lines, data lines, switching elements, storage lines, pixel electrodes, and an organic insulation layer. The gate lines and the data lines define a plurality of unit pixels. The storage lines are respectively formed adjacent to the respective drain electrodes of the respective switching elements of respective rows of the unit pixels. The organic insulation layer has a hole that is formed within the area of each of the unit pixels and that extends from a contact area formed at a portion of the corresponding drain electrode of the pixel to a portion corresponding to the storage line thereof. This arrangement enables the marginal area needed to prevent mismatch of the hole in the areas of the contact area and the storage line to be reduced, thereby increasing the aperture ratio of the display.
    • 显示基板包括多条栅极线,数据线,开关元件,存储线,像素电极和有机绝缘层。 栅极线和数据线限定多个单位像素。 存储线分别形成为与各行的单位像素的各个开关元件的各个漏电极相邻。 有机绝缘层具有形成在每个单位像素的区域内的孔,并且从形成在像素的相应漏电极的一部分的接触区域延伸到对应于其存储线的部分。 这种布置使得能够减小接触区域和存储线的区域中的孔的失配所需的边缘区域,从而增加显示器的开口率。
