We have investigated ultra-high contrast display using dual-cell liquid crystal display (LCD) technology. Dual-cell LCDs have issues such as moiré and color unevenness. Thus, we have developed a dual-cell LCD that solved these issues by arranging a light-shielding pattern in the diagonal direction of the subpixel pitch in a dimming cell.
