Patent number: 9086587Abstract: In a liquid crystal display (LCD), a thickness of a passivation layer overlapping signal lines is larger than a thickness of portion of the passivation layer not overlapping signal lines. A spacer may be formed to overlap the signal lines. In an aperture region of the LCD, a thickness of the passivation layer between a common electrode and a pixel electrode is relatively small, and therefore, it may be possible to prevent reduction in the intensity of the electric field between the common electrode and the pixel electrode. Since thickness of the passivation layer may be relatively large, it may be possible to prevent a signal delay of common voltage. A spacer may be formed overlapping signal lines with relatively thick passivation layer. The spacer may have a small height. Cell gap may be adjusted to be uniform, and prevent reduction in aperture ratio of the LCD.Type: GrantFiled: March 14, 2013Date of Patent: July 21, 2015Assignee: Samsung Display Co., Ltd.Inventors: Gyung-Soon Park, Il Gon Kim

Patent number: 8730422Abstract: A liquid crystal display uses a layout which reduces the number of data lines relative to the number of pixel columns by providing one data line for every two pixel columns. The display is structured to prevent a passivation layer from becoming opaque due to a manufacturing haze effect by forming the pixel electrode below a gate insulating layer. It is structured to prevent a drain electrode from being damaged due to an etchant used for patterning the pixel electrode. Further, it is structured to prevent a short circuit between a common voltage line and a gate line while not substantially reducing an aperture ratio by disposing a common voltage contact hole for electrically connecting the common voltage line with a common electrode between vertically extending portions of two gate lines that generally extend horizontally.Type: GrantFiled: September 13, 2012Date of Patent: May 20, 2014Assignee: Samsung Display Co., Ltd.Inventors: Gyung-Soon Park, Il Gon Kim, Seon Young Choi, Sung Hoon Kim
