Abstract New peeping prevention technology to control the viewing angle properties of TFT‐LCDs has been developed. This technology can be applied to all kinds of LCDs, especially to the ones for PCs, cellular phones, ATMs and so on. In this technology, an additional LC panel in which the whole area is divided into two kinds of small visible domains of different LC alignment directions is used. The products, named VAC Filter™ or VACF™, have been put on sale in 2003 and have been applied to TOSHIBA TECRA M3 and so on.
