Patent number: 9633615Abstract: An LCD device is disclosed. The liquid crystal display device includes a capacitor formed between the input terminal of an internal driving circuit and a LOG type signal line, which receive the start pulse signal. Therefore, the LCD device can stably drive its internal driving circuit, even though static electricity is generated on the LOG signal line which is used for transferring the start pulse signal of a short enabling time.Type: GrantFiled: November 11, 2009Date of Patent: April 25, 2017Assignee: LG Display Co., Ltd.Inventors: Il Man Choi, Myeong Hoon Kwon

Patent number: 8703554Abstract: An array substrate for an LCD device includes a gate line crossing a data line to define a pixel region. A thin film transistor (TFT) includes a gate electrode connected to the gate line, insulating and active layers on the gate electrode, a source electrode connected to the data line, and a drain electrode spaced apart from the source electrode. An auxiliary common electrode includes a horizontal portion disposed in the pixel region. A metal layer overlaps the insulating layer and contacts the horizontal portion of the auxiliary common electrode through a contact hole defined through the insulating layer. A passivation layer is disposed on the TFT and the metal layer. A pixel electrode has a horizontal portion overlapping the metal layer with the passivation layer therebetween to form a storage capacitor, the pixel electrode connected to the drain electrode through a second contact hole defined through the passivation layer.Type: GrantFiled: November 28, 2012Date of Patent: April 22, 2014Assignee: LG Display Co., Ltd.Inventors: Il-Man Choi, Ho-June Kim

Patent number: 8416359Abstract: Array substrates for liquid crystal display (LCD) devices are formed on a substrate with first and second gate lines crossing a data line to define first and second pixel regions. A thin film transistor includes a source electrode and a drain electrode. A metal pattern overlaps a common line and makes up a portion of the drain electrode. A passivation layer is disposed on the source and drain electrodes and on the metal pattern. A first pixel electrode is connected to the metal pattern and a common electrode is connected to the common line. Various repair patterns are formed to define one or more repairing portions that enable connection of the drain electrode or metal pattern to a second pixel electrode of the second pixel region if the cut line is cut in the event the first pixel electrode fails to display an image.Type: GrantFiled: July 28, 2010Date of Patent: April 9, 2013Assignee: LG Display Co., Ltd.Inventors: Il-Man Choi, Tae-Hyeung Kim, Min-Jic Lee
