    摘要: A display substrate includes a gate line, a storage capacitor, a source line, a switching element, a pixel electrode, and a color filter. The gate line is formed on a base substrate. The storage capacitor has a storage line substantially parallel to the gate line. The source line crosses the gate line to define a pixel area. The switching element is connected to the gate line and the source line. The pixel electrode contacts the switching element. The color filter pattern is formed between the base substrate and the pixel electrode such that the color filter pattern contracts the base substrate and the pixel electrode. Thus, the color filter pattern is formed on the display substrate using a three-mask process.

    摘要: A method of manufacturing a TFT substrate includes: sequentially forming a transparent conductive layer and an opaque conductive layer on a substrate, patterning the transparent conductive layer and the opaque conductive layer by using a first mask to form a gate pattern including a pixel electrode, and forming a gate insulating layer and a semiconductor layer above the substrate. A contact hole is formed which exposes a portion of the pixel electrode and a semiconductor pattern using a second mask. A conductive layer is formed above the substrate and patterned to form a source/drain pattern including a drain electrode which overlaps a portion of the pixel electrode. Portions of the gate insulating layer and the opaque conductive layer above the pixel electrode are removed except a portion overlapping the drain electrode, by using a third mask.

    摘要: A display substrate includes a base substrate, a thin-film transistor (TFT), a pixel electrode, a pad part, and a cell-gap compensating part. The base substrate has a display region, a seal region surrounding the display region, and a peripheral region surrounding the seal region. The TFT is in the display region. The pixel electrode is connected to a drain electrode of the TFT and contacts the base substrate. The pad part is interposed between a first side of the base substrate and the seal region and is connected to the TFT through a first transmission line. The cell-gap compensating part is in the seal region and includes a compensating pattern adjacent to a second side of the base substrate and an insulating pattern on the compensating pattern.

    摘要: A method for manufacturing a thin film transistor array panel using a photo mask is provided. The photo mask includes: a transmitting area and a translucent area, wherein the translucent area includes a plurality of light blocking portions blocking light, and wherein the light blocking portions have a plurality of areas blocking different amounts of light. By using this type of photo mask, a substantially flat layer of photoresist film can be deposited even on top of an uneven surface to manufacture a thin film transistor array panel. The flat photoresist film reduces processing cost and enhances the reliability of the panel manufacturing process.
