| 20080237037 | MASK AND METHOD OF MANUFACTURING THE SAME - A mask includes a transparent substrate, a light-blocking layer and a halftone layer. The light-blocking layer includes a source electrode pattern portion including a first electrode portion, a second electrode portion and a third electrode portion, and a drain electrode pattern portion disposed between the second electrode portion and the third electrode portion. The halftone layer includes a halftone portion corresponding to a spaced-apart portion between the source electrode pattern portion and the drain electrode pattern portion, and a dummy halftone portion more protrusive than ends of the second electrode portion and the third electrode portion. Thus, a photoresist pattern corresponding to a channel portion of a thin film transistor (TFT) may be formed with a uniform thickness, to thereby prevent an excessive etching of the channel portion. | 10-02-2008 |
| 20090135347 | DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF - A manufacturing method of a display device, wherein the manufacturing method for an embodiment includes: forming color filters in a plurality of pixel regions; forming a conductive layer on the color filters; and separating the conductive layer in each of the pixel regions through a photolithography process and forming a pixel electrode; wherein a groove is formed between the adjacent color filters having different colors at boundaries between the pixel regions; and wherein the photolithography process uses a negative photoresist material. | 05-28-2009 |
| 20090159888 | DISPLAY PANEL AND METHOD FOR MANUFACTURING THE SAME - A display panel and a manufacturing method thereof which includes forming a color filter on an insulating substrate, forming a plurality of trenches in the color filter, forming a first metal layer in the trenches, forming a second metal layer on the first metal layer to form gate lines, forming a gate insulating layer on the color filter and the gate lines, forming a semiconductor on the gate insulating layer, forming data lines including source electrodes and drain electrodes, and forming pixel electrodes connected to the drain electrodes. | 06-25-2009 |
| 20090176325 | HALFTONE MASK, METHOD OF MANUFACTURING THE SAME, AND METHOD OF MANUFACTURING AN ARRAY SUBSTRATE USING THE SAME - A halftone mask includes a transparent substrate, a light-blocking layer, a first semi-transparent layer and a second semi-transparent layer. The transparent substrate includes a light-blocking area, a light-transmitting area, a first halftone area transmitting first light, and a second halftone area transmitting second light that is less than the first light. The light-blocking layer is formed in the light-blocking area to fully block light from being transmitted. The first and second semi-transparent layers are formed on the transparent substrate. At least one of the first and second semi-transparent layers is formed in the first halftone area, and the first and second semi-transparent layers are overlapped with each other on the second halftone area. | 07-09-2009 |
| 20100055851 | PHOTORESIST COMPOSTION, METHOD FOR FORMING THIN FILM PATTERNS, AND METHOD FOR MANUFACTURING A THIN FILM TRANSISTOR USING THE SAME - The present invention relates to a photoresist composition that comprises a resin that is represented by Formula 1, a method for forming a thin film pattern, and a method for manufacturing a thin film transistor array panel by using the same. | 03-04-2010 |
| 20100167476 | PHOTORESIST COMPOSITION AND METHOD OF FABRICATING THIN FILM TRANSISTOR SUBSTRATE - The present invention relates to a photoresist composition for digital exposure and a method of fabricating a thin film transistor substrate. The photoresist composition for digital exposure includes a binder resin including a novolak resin and a compound represented by the chemical formula (1), a photosensitizer including a diazide-based compound, and a solvent: | 07-01-2010 |
| 20110051059 | ORGANIC LAYER COMPOSITION AND LIQUID CRYSTAL DISPLAY USING THE SAME - An organic layer composition and a liquid crystal display including the same are provided. An organic layer composition according to an exemplary embodiment includes a binder formed by copolymerizing compounds included in a first group and a second group, wherein the first group includes an acryl-based compound and the second group includes a compound without a —COO— group. | 03-03-2011 |
