摘要： 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.

摘要： A vertical alignment liquid crystal display includes two sub-pixels each with a variable capacitor. A pixel is bisected into a high gray sub-pixel and a low gray sub-pixel through forming a variable capacitor at each sub-pixel. With this structure, the sub-pixels express different grays so that lateral visibility is enhanced. It is not required in bisecting a pixel into two sub-pixels to form separate wires for applying different signals thereto, and the amount of data to be processed at the driver for driving the display device is reduced. Furthermore, a pixel is bisected into two sub-pixels with variable capacitors in a simplified manner, and it is not required to form additional wires and elements, so the aperture ratio is enhanced.

摘要： A display apparatus according to one or more embodiments includes an array substrate and an opposite substrate facing the array substrate. Pixels areas are defined in the array substrate, and each pixel area includes a pixel electrode having concave-convex patterns at the edges thereof when viewed in a plan view. The concave-convex patterns vary directions of fringe fields generated from the edges of the pixel electrode, so that an area in which a fringe field is formed relative to one pixel area may be prevented from overlapping with a peripheral pixel area.

摘要： There are provided an organic EL device and a method of fabricating the same. An effective display area on which an anode electrode, an organic luminescence layer and a cathode electrode are formed is sealed by means of a metal can, a glass cap or an organic/inorganic material. A power source is applied to the anode and the cathode electrodes through a power transferring part extended from the effective display area to a non-effective display area. Accordingly, it is possible to reduce the oxidation of the cathode electrode of the organic EL device, thereby preventing the electrical contact characteristics of the cathode electrode from being deteriorated.

摘要： Disclosed are an active matrix type organic electroluminescent display device and a manufacturing method thereof. At least two capacitors having different functions from each other are disposed in a vertically stacked structure within a unit pixel region. When a compensation circuit needing two or more capacitors having different functions from each other per pixel is applied, the two or more capacitors are vertically stacked, thereby preventing the aperture ratio from being lowered due to the increase in the number of capacitors within the pixel.
