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.
