Abstract
A liquid crystal display includes a pair of substrates and a liquid crystal layer interposed between the substrates and has a reflective area and a transmissive area. At least one of the substrates is provided with a retardation film whose phase difference differs between the reflective area and the transmissive area. Alternatively, at least one of the substrates is provided with a retardation film whose slow axis differs between the reflective area and the transmissive area.
Claims26
A liquid crystal display comprising:
- a pair of substrates;
- and
- a liquid crystal layer interposed between the substrates,
- wherein the liquid crystal display has a reflective area and a transmissive area,
- wherein at least one of the substrates is provided with a retardation film whose phase difference differs between the reflective area and the transmissive area, and
- wherein the liquid crystal layer has a phase difference of λ/4 in the reflective area and is in a 90° twisted nematic state in the transmissive area when no voltage is applied or when a voltage is applied.
A method for manufacturing a liquid crystal display which has a pair of substrates and a liquid crystal layer interposed between the substrates and which has a reflective area and a transmissive area, the method comprising the steps of:
- forming a retardation film on at least one of the substrates;
- patterning the retardation film such that the retardation film remains at least in the reflective area and the phase difference of the retardation film differs between the reflective area and the transmissive area, and
- further comprising the step of forming an alignment film by photoalignment such that the alignment direction of the alignment film differs between the reflective area and the transmissive area on a surface of at least one of the substrates which faces the liquid crystal layer.
A liquid crystal display comprising:
