Patent ID: 7224419

Claim:
A liquid crystal display device, comprising: a first substrate; a second substrate comprising a thin film transistor array thereon; a black matrix on one of the first substrate and the second substrate; a color filter between the black matrix; a liquid crystal layer between the first substrate and the second substrate; a patterned first electro-magnetic interference shield layer on the first substrate and exposing a portion of the first substrate, wherein the position of the first electro-magnetic interference shield layer corresponds to the position of the black matrix, and the patterned first electro-magnetic interference shield layer is a conductive material and not electrically connected to the thin film transistor array, and wherein the material of the first electro-magnetic interference shield layer is selected from the group consisting of non-transparent materials and transparent materials; and a second electro-magnetic interference shield layer on the first substrate covering the first electro-magnetic interference shield layer, wherein the material of the second electro-magnetic interference shield layer is a transparent material.
