Passive liquid crystal display having pre-tilt control structure and light absorbent material at a center

摘要

In accordance with the present invention, a passive liquid crystal display cell includes a first substrate having a light absorbent material patterned thereon. A first conductive material is formed in a position relative to the light absorbent material for forming one of a data line and a gate line. The position may be over the light absorbent material or below the light absorbent material (and may include transparent layers in between). A second conductive material is spaced apart from the first conductive material by a gap. The gap includes liquid crystal, and the second conductive material forms the other of the data line and the gate line. A pretilt control structure is formed adjacent to the liquid crystal. The gate line and the data line provide an electric field therebetween wherein the pretilt control structure provides pretilt for the liquid crystal to provide a wide viewing angle.
