  • Publication number: 20170160617
    Abstract: A liquid crystal display with two insulating substrates. A first insulating substrate has crossing signal lines, a pixel electrode, and a drain electrode electrically connected to the pixel electrode through a contact hole. A spacer is formed on the first signal line of the first insulating substrate, and is wider at a first portion close to the first insulating substrate than at a second portion close to the second insulating substrate, and the drain electrode comprises a first portion and a second portion extending in a different direction with respect to the first portion.

  • Publication number: 20110285952
    Abstract: A liquid crystal display includes first and second substrates. The first substrate has a first insulating substrate, and a pixel electrode formed on the first insulating substrate with a first opening pattern. The second substrate has a second insulating substrate, and a common electrode formed on the second insulating substrate with a second opening pattern. The first and the second opening patterns proceed parallel to each other while being arranged in an alternate manner. A liquid crystal material is injected between the first and the second substrates. A spacer is positioned at an end of the second opening pattern to maintain the distance between the first and the second substrates.
