Abstract
A liquid crystal display includes a liquid crystal display panel including a thin film transistor (TFT) array substrate, an opposed substrate, and a liquid crystal layer between the TFT array substrate and the opposed substrate. A lower polarizer is disposed on a side of the TFT array substrate facing away from the liquid crystal layer, and the opposed substrate is provided with a polarization analyzer. The polarization analyzer includes a plurality of polarization regions and a plurality of non-polarization regions. A portion of the polarization analyzer corresponding to the polarization region is a polarization device, and the polarization regions and non-polarization regions are arranged alternately. The LCD can improve the security and confidentiality of the information displayed on the LCD when a user views the information. And special eyeglasses and display apparatus are also provided.
