  • Patent number: 9116402
    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: 20120133874
    Abstract: In one embodiment, a liquid crystal display panel includes an array substrate and a counter substrate each having a display region and a peripheral region arranged adjacent to the display region. A resin layer is formed either one of the array substrate and the counter substrate. A protrusion in the shape of a wall is arranged on the resin layer with a gap between the protrusion and the substrate opposing the protrusion. A seal material is formed between the array substrate and the counter substrate, and arranged between a peripheral portion of the display region and the protrusion for attaching the array substrate and the counter substrate. A liquid crystal layer is formed in a surrounded region by the array substrate, the counter substrate and the seal material.
