Patent ID: 7327419

Claim:
A liquid crystal display device (LCD) comprising a TFT substrate, a color filter substrate, and a twisted nematic liquid crystal (LC) layer sandwiched between said TFT substrate and said color filter substrate, said color filter substrate comprising: a transparent substrate; a light shield layer formed on said transparent substrate and having a substantially lattice pattern; a coloring layer formed on a portion of said transparent substrate within each space of said light shield layer and on an edge portion of a stripe of said light shield layer; and an orientation film overlying said coloring layers and the other portions of said stripes of said light shield layer, said coloring layer having a substantially flat surface overlying said space of said light shield layer, a slope surface having a width of not more than 2.575 μm extending and rising from said flat surface and overlying said edge portion of said stripe of said light shield layer, a polished flat surface extending from said slope surface, and a rear edge surface extending between said polished flat surface and said other portion of said stripe of said light shield layer, wherein the following relational expression holds: D = 2 ⁢ ϕ - ( 0.25 ⁢ ⁢ θ + 1 + L 1 / 4 - 1.034 0.03724 ) > 0 , where the θ, L and φ represent an angle of said slope surface with respect to a surface of said transparent substrate, a width of said slope surface, and a pre-tilt angle of LC molecules in said LC layer, respectively.
