Patent number: 8284339Abstract: A column for defining the interval between a TFT substrate and an opposed substrate is formed at a crossing point between a drain line and a scanning line. At the crossing point where the column is formed, the drain line is formed to have a wider width to prevent light leakage. Further, at the crossing point where the column is formed, the scanning line is formed to have a narrower width to prevent increase of capacitance between the drain line and the scanning line. The column is formed at a crossing point corresponding to a specific color, e.g., a blue pixel B, so that a difference in transmittance and in characteristic of thin film transistors due to formation of the column is initially compensated.Type: GrantFiled: February 19, 2009Date of Patent: October 9, 2012Assignees: Hitachi Displays, Ltd., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Takahiro Ochiai, Tohru Sasaki, Tetsuya Nagata

Patent number: 8274636Abstract: A method of forming a spacer for a liquid crystal display (LCD) device is disclosed. To form the spacer, an ink jet injection nozzle is aligned over a substrate on which unit pixels are arranged in a matrix. After aligning the nozzle, first dispensing spacers are dispensed from the injection nozzle with a certain gap so that at least one unit pixels is interposed between the spacers. Subsequently, the nozzle is moved and second dispensing spacers are dispensed by the nozzle at each of the unit pixels formed between the first spacers. This is repeated until the spacer is formed at all unit pixels. The spacer contains a ball spacer and a volatile liquid, which is vaporized during dispensing. The ink jet injection method prevents adjacent spacers from interfering with each other during formation.Type: GrantFiled: November 8, 2005Date of Patent: September 25, 2012Assignee: LG Display Co., Ltd.Inventors: Min-Joo Kim, Jeong-Hyun Kim, Myoung-Ho Lee
