  • Patent number: 10365524
    Abstract: A liquid crystal display in which the common voltage line is disposed directly on or directly under the common electrode directly contacts the common electrode such that a signal delay of the common voltage line may be reduced and simultaneously a reduction in the aperture ratio of the liquid crystal display may be prevented.
    Type: Grant
    Filed: November 6, 2017
    Date of Patent: July 30, 2019
    Assignee: Samsung Display Co., Ltd.

  • Patent number: 7929096
    Abstract: A liquid crystal display includes a first insulating substrate, pixel electrodes disposed on the first insulating substrate and divided into a plurality of domains, each domain including micro-concave stripes and micro-convex stripes arranged in a specific direction, a second insulating substrate facing the first insulating substrate, a common electrode, which is not patterned, disposed on the second insulating substrate, and a liquid crystal layer interposed between the first and second insulating substrates and including liquid crystal molecules. The liquid crystal molecules are aligned perpendicular to the first and second insulating substrates when an electric field is not applied to the liquid crystal layer, and the liquid crystal molecules are inclined in an extension direction of the micro-concave stripes and the micro-convex stripes when an electric field is applied to the liquid crystal layer.

  • Publication number: 20030000473
    Abstract: A method of delivering two or more mutually-reactive reaction gases when a predetermined film is deposited on a substrate, and a shower head used in the gas delivery method, function to increase the film deposition rate while preventing formation of contaminating particles. In this method, one reaction gas is delivered toward the edge of the substrate, and the other reaction gases are delivered toward the central portion of the substrate, each of the reaction gases being delivered via an independent gas outlet to prevent the reaction gases from being mixed. In the shower head, separate passages are provided to prevent the first reaction gas from mixing with the other reaction gases by delivering the first reaction gas from outlets formed around the edge of the bottom surface of the shower head. The other reaction gases are delivered from outlets formed in the central portion of the bottom surface of the shower head.
