Improvement Technology of LCD Display
6-3 Multi-Domain System
The arrangement of the TN LCD display is one directional. In this Multi-Domain System, one pixel is
divided into two or more different arranged domains.
Fig. 23 shows the example of Multi-Domain System with two domains. The quantity of the light per pixel
from various angles is equalized by this system. Moreover, the angle of view becomes even wider by
increasing the number of divisions. However, manufacturing is difficult in the rubbing process*.
