20090153785Liquid Crystal Display Device - An object of the present invention is to form spacers for defining the space between the TFT substrate and the facing substrate of color filters, and by doing so, finely control the height of the spacers. First spacers 06-18-2009
20100214205LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device includes pixels, each of which includes a first transistor and a second transistor. The size of the first transistor is larger than the size of the second transistor. In addition, channel widths and gate widths for the first transistor are larger than those of the second transistor. Also, the first transistor is located to be closer to a drain signal line provided for the pixel than the second transistor. In normal operation, the first transistor is coupled to the drain signal line and the second transistor is floating. However, if an abnormality occurs in the first transistor, it is cut off from the drain signal line and the second transistor is connected to the drain signal line by a repair line.08-26-2010
20100328588PANEL FOR LIQUID CRYSTAL DISPLAY DEVICE - A panel for a liquid crystal display device includes: a first mother substrate for cutting out color filter substrates including a first cell area corresponding to a first cell and a second cell area corresponding to a second cell therefrom; a first colored layer arranged in the first cell area of the first mother substrate; a second colored layer arranged in the second cell area of the first mother substrate; a second mother substrate for cutting out array substrates therefrom; and liquid crystal sandwiched between the first mother substrate and the second mother substrate. The first colored layer and the second colored layer are made of the same material and have portions which have the same thickness. A hole is formed in the second colored layer so as to make color reproducibility of the second colored layer lower than color reproducibility of the first colored layer.12-30-2010
20110042675Display device and manufacturing method thereof - An etching resist including first and second portions, the first portion being thicker than the second portion, is formed on a metallic layer. Through the etching resist, a semiconductor layer and the metallic layer are patterned by etching so as to form a wiring from the metallic layer and leave the semiconductor layer under the wiring. An electrical test is conducted on the wiring. The second portion is removed while the first portion is left unremoved. Selective etching is performed through the first portion so as to leave the semiconductor layer unetched to pattern the wiring to be divided into drain and source electrodes. A substrate is cut. In patterning the wiring, the wiring is etched to be cut at a position closer to a cutting line of the substrate with respect to the drain and source electrodes, while leaving the semiconductor layer unetched.02-24-2011
