  • Publication number: 20150316822
    Abstract: An array substrate includes a gate line extending in a first direction, a source line extending in a second direction orthogonally crossing the first direction and an auxiliary capacitance line having a trunk portion extending in the first direction so as to cross the source line and a branch portion branched from the trunk portion and extending along the source line. A switching element includes a drain line arranged under the auxiliary capacitance line so as to face the trunk portion and the branch portion thereof. A pixel electrode includes a main pixel electrode extending substantially in parallel to the source line and a contact portion electrically connected with the drain line. A counter substrate includes a couple of main common electrodes extending substantially in parallel to the main pixel electrode on the both sides sandwiching the main pixel electrode.

  • Publication number: 20150286104
    Abstract: In one embodiment, a first shield electrode and a second shield electrode are arranged on a first substrate. A first source line and a second source line are arranged facing the first and second shield electrodes through an insulating layer, respectively. A first main common electrode and a second main common electrode are formed facing the first and second source lines through an insulating layer, respectively. A main pixel electrode is formed so as to locate between the first and second main common electrodes. A second substrate includes a third main common electrode and a fourth main common electrode facing the first and second main common electrodes, respectively. A liquid crystal layer is held between the first and second substrates. The first, second, third and fourth main common electrodes are set to the same electric potential.
