  • In-plane switching mode liquid crystal display device capable of shielding against interferences
    Patent number: 6400435
    Abstract: An in-plane switching mode liquid crystal display device includes first and second substrates having facing inner surface, a common electrode and a data electrode formed in a pixel region, a passivation layer and a first alignment layer deposited on the first substrate, a light shielding layer on the second substrate, a color filter layer, and a second alignment layer formed on the light shielding layer in sequence, an electric field shielding layer formed on an opposing surface of the second substrate, wherein the electric field shielding layer includes a transparent metal such as ITO, a discharge member electrically coupled to the electric field shielding layer, an analyzer on the electric field shielding layer, and a liquid crystal layer between said first and second substrates.
