| 摘要 |
The invention pertains to a single-polarizer, normally white reflective display comprising an STN-LCD cell, a reflector, one polarizer, and a twisted retardation layer, wherein the sign of the twist angle of the STN-LCD cell (TSTN) is opposite to the twist angle of the twisted retardation layer (TRL) and |TSTN-TRL| is between 90° and 160°, and |RSTN-RRL| is 10-700 nm, wherein RSTN and RRL stand for the retardation values of the STN-LCD cell and the retardation layer, respectively, and the difference between the dispersion of the retardation layer and the STN-LCD cell is more than 5%, wherein the dispersion is defined as the ratio of the retardation value at lambd=436 nm to the retardation value at lambd=668 nm.
