Abstract
Liquid crystal display in which a twisted nematic type liquid crystal cell is disposed between a linear polarizer and a guest-host type liquid crystal cell with homogeneous alignment and an electric field is selectively applied externally to arbitrary liquid crystal layers. Electro-optical control of inverted display of positive-to-negative images, complicated figure display and multi-color display is made possible.
