Electro-optical display device using a liquid crystal cell

摘要

An electro-optical display device and a method of manufacturing it are disclosed. The display device includes a liquid crystal cell arranged between two polarizers. A light source is positioned adjacent one polarizer on the side thereof remote from the liquid crystal cell, and an electronic control device is coupled to the liquid crystal cell. A diaphragm is arranged on one side of the liquid crystal cell in the form of an aperture for limiting the display field of the liquid crystal. The device limits viewing parallax and improves contrast for both day and night viewing.
