Beschreibung
Zusammenfassung:	PURPOSE:To enlarge a visual field range and improve constrast by setting the refractive index anisotropy of liquid crystal materials and the product of thickness of liquid crystal layers at below specific values and providing a color display of the ground color similar to the liquid crystal color by using color polarization plates in a TN type liquid crystal display element. CONSTITUTION:In a TN type liquid crystal display element, the value of DELTAn.d is so set as to attain
