Provided is a display device integrated with a touch screen panel including a display unit including a plurality of pixels at a sealed region between a lower substrate and an upper substrate; first touch electrodes extending in a first direction on the upper substrate over the sealed region, wherein ends of the first touch electrodes extend to a non-sealed region on the lower substrate; and a sloped portion beneath the first touch electrodes at a boundary between the sealed region and the non-sealed region.

In a display apparatus and a manufacturing method of the display apparatus, the display apparatus includes a display panel having signal lines and an insulating layer, and a signal generator electrically connected to the signal lines and adhering to the display panel. The signal lines include pads formed at ends thereof, respectively. The organic insulating layer is partially removed such that the via holes are formed between the pads of the signal lines to reduce a step-difference between an area in which the pads are formed and an area in which the pads are not formed. Thus, the display apparatus may enhance the coupling force between the signal generator and the display panel.

A method for manufacturing a semiconductor device is disclosed, which reduces a step difference between a peripheral region and a cell region. In the semiconductor device, a metal contact of the peripheral region is configured in a multi-layered structure. Prior to forming a bit line and a storage node contact in the cell region, a contact and a line are formed in the peripheral region, such that a step difference between the cell region and the peripheral region is reduced, resulting in a reduction in parasitic capacitance between lines.

Provided are an organic light emitting display device and a method for manufacturing the same. A color filter is disposed on a substrate. An overcoating layer is disposed on the color filter and includes a plurality of protrusions or a plurality of recesses. The plurality of protrusions and the plurality of recesses are disposed on the color filter to be overlapped with the color filter. A buffer layer for reducing step difference is disposed on the overcoating layer. The buffer layer has a higher refractive index than the overcoating layer and reduces a step difference caused by the plurality of protrusions and the plurality of recesses. An organic light emitting element including an anode, an organic light emitting layer, and a cathode is disposed on the buffer layer. Since the buffer layer has a higher refractive index than the overcoating layer, light extraction efficiency can be increased.

A metal wiring layer and a method of fabricating the metal wiring layer are provided. The method includes forming a dielectric layer on a substrate, forming a plurality of dielectric layer patterns and holes therein on the substrate by etching part of the dielectric layer, with a cross sectional area of the holes in the dielectric layer patterns decreasing with increasing distance away from the substrate and the holes exposing the substrate, forming a trench by etching a portion of the substrate exposed through the holes in the dielectric layer patterns, and forming a metal layer which fills the trench and the holes in the dielectric layer patterns. Thus, it is possible to prevent the occurrence of an edge build-up phenomenon by forming a metal layer in a plurality of holes in the dielectric layer patterns having a cross sectional area decreasing with increasing distance away from the substrate. Therefore, it is possible to prevent the transmittance of a liquid crystal layer from decreasing due to a failure to properly fill liquid crystal molecules in the liquid crystal layer, and thus to increase the quality of display.

An organic thin film transistor (TFT), a method of making and a display including the organic TFT. In the TFT, the disconnection of a channel region does not occur because a step difference between a substrate and source and drain electrodes is lessened or eliminated by forming the source and drain electrodes in grooves in a buffer film. The method of manufacturing the organic TFT includes forming a buffer film on a substrate, forming concave units separated by a distance from each other in the buffer film by etching the buffer film, forming an electrode layer on the buffer film, forming source and drain electrodes within the concave units by etching the electrode layer using a photolithography process, forming a semiconductor layer on the source and drain electrodes and on the buffer film, forming a gate insulating film on the semiconductor layer and forming a gate electrode on the gate insulating film.
