Zusammenfassung:In one aspect, a liquid crystal cell is provided, having: a spacer stiffness factor in the range of at least 0.01 MPa-mm to not greater than 1 MPa-mm, a cross-sectional thickness of the cell gap is configured to vary not greater than 6.5% of the target cell gap cross-sectional thickness, as measured along the length of the liquid crystal cell, and the liquid crystal cell has a pressure underfill of not greater than 10 vol. %. Selon un aspect de l'invention, l'invention concerne une cellule à cristaux liquides, ayant : un facteur de rigidité d'espaceur dans la plage d'au moins 0,01 MPa-mm à pas plus de 1 MPa-mm, une épaisseur de section transversale de l'espace de cellule est configurée pour ne pas dépasser 6,5 % de l'épaisseur de section transversale de l'espace de cellule cible, telle que mesurée le long de la longueur de la cellule à cristaux liquides, et la cellule à cristaux liquides a un manque de remplissage sous pression supérieur ou égal à 10 % en volume.
