Abstract
A reflection type liquid crystal display comprises first and second substrates disposed facing each other and holding a liquid crystal exhibiting a negative dielectric constant anisotropy between them, the first substrate ( ) has on the side of its surface facing the second substrate a TFT as a switching element, a reflective display electrode ( ) formed of a conductive reflective material and connected to the TFT and a vertical alignment film for vertically aligning the liquid crystal molecules. The second substrate ( ) has on the side facing the first substrate a counter electrode ( ) including an alignment control window ( ) for controlling the alignment of the liquid crystal molecules and an alignment film. The second substrate ( ) has on the viewing side of the display, the side of its surface not facing the first substrate, a phase plate ( ) and a polarizer ( ) forms. A light diffusing layer is formed on the side of the second substrate facing or not facing the first substrate. With this configuration, the display device when viewed from the viewing side is free of the occurrence of parallax and provides a wide viewing angle.
