  • Patent number: 7095469
    Abstract: A multi-domain liquid crystal display device comprises first and second substrates facing each other; a liquid crystal layer between the first and second substrates; a plurality of gate bus lines arranged in a first direction on the first substrate and a plurality of data bus lines arranged in a second direction on the first substrate to define a plurality of pixel region; a thin film transistor positioned at a crossing area of the data bus line and the gate bus line, the thin film transistor comprising a gate electrode, a semiconductor layer, and source/drain electrodes; a common-auxiliary electrode comprising at least one electrode in the each pixel region; a plurality of pixel electrodes electrically charged through the thin film transistor; and an alignment layer on at least one substrate between the first and second substrates.

  • Patent number: 7095458
    Abstract: The present invention relates to an identification mark portion and fabricating method thereof, more particularly, to an identification mark portion introduced in a liquid crystal display panel and a fabricating method thereof, which minimizes the error in verifying an ID of a pad by preventing at least two insulating layers from overlapping each other over the upper part of the pad. The present invention includes an insulating substrate, an ID mark pad including an ID mark on the insulating substrate, and a first insulating layer and a second insulating layer on the insulating substrate wherein the first and second insulating layers expose the ID mark in the ID mark pad. In another aspect, the present invention includes the steps of forming an ID mark pad including an ID mark on an insulating substrate, and forming a first and a second insulating layer which expose the ID mark in the ID mark pad.
