Liquid crystal display and method for manufacturing the same related application data
View Patent ↗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.
1. 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,
at least one of the substrates is provided with a retardation film whose phase difference differs between the reflective area and the transmissive area,
the liquid crystal layer has a phase difference of λ/4 in the reflective area, where λ is the wavelength of light, and is in a 90° twisted nematic state in the transmissive area when no voltage is applied or when a voltage is applied, and
the liquid crystal layer displays an image in an electrically controlled birefringence mode in the reflective area and in a twisted nematic mode in the transmissive area.
2. The liquid crystal display according to claim 1 , wherein the liquid crystal layer is in a twisted nematic state in the reflective area when no voltage is applied or when a voltage is applied.
