Abstract— We have developed an advanced axially symmetric aligned microcell mode using negative‐dielectric liquid crystal (N‐type ASM mode), the first in the world. Using compensation film for this N‐type ASM mode cell realizes the wide viewing angle of ±,80° in all azimuths, and a high contrast ratio of 300:1. The structure of this N‐type ASM‐mode panel is suitable for large‐sized display panels. This mode is applicable for such active display panels as TFT and PALC 1 displays, regardless of the difference of their drive systems. We consider that this N‐type ASM mode will be a key technology for next‐generation monitors.
