Les cristaux liquides se retrouvent aujourd’hui dans nombreuses applications. La phase cristal liquide la plus connue et la plus utilisée est la phase nématique. En 2011 une nouvelle phase, la phase Nématique Twist Bend (NTB), a été découverte. Très prometteuse pour de futures applications, elle pourrait stimuler le développement d’une nouvelle génération de dispositifs électro-optiques. Deux problèmes principaux limitent cependant son utilisation. La phase NTB est difficile à orienter sur de grandes surfaces. Un second défi réside dans l’obtention d’une phase NTB stable à température ambiante. Les travaux de cette thèse sont focalisés sur ces deux problématiques.La mauvaise orientation de la phase NTB dans des cellules planaires se traduit...
