Abstract:
A passive liquid crystal display cell comprising:a first substrate having a light absorbent material patterned thereon wherein the light absorbent material includes a conductive black matrix material; a first transparent conductive material formed in a position relative to the light absorbent material, the position being one of over the light absorbent material and below the light absorbent material for forming one of a data line and a gate line; a dielectric layer formed between the light absorbent material and the first conductive material; a second conductive material spaced apart from the first conductive material by a gap, the gap including liquid crystal, the second conductive material for forming the other of the data line and the gate line; a pretilt control structure formed adjacent to the liquid crystal, wherein the pretilt control structure is self-aligned to the portions of the light absorbent material at the crossover, and the pretilt control structure and the light absorbent material are disposed at a center of one of the first transparent conductive material and the second conductive material; and the gate line and the data line for providing an electric field therebetween wherein the pretilt control structure provides pretilt for the liquid crystal to provide a viewing angle.
