Title (EN) LIGHT-SENSITIVE POLYMER AND ALIGNMENT LAYER INCLUDING SAME
(FR) POLYMÈRE PHOTOSENSIBLE ET COUCHE D'ALIGNEMENT LE COMPRENANT
(KO) 광반응성 중합체 및 이를 포함하는 배향막
Abstract: front page image
(EN)The present invention relates to a light-sensitive polymer and to an alignment layer including same, exhibiting superior alignment speed and alignment stability. The light-sensitive polymer comprises a ring-type olefin-based repeating unit having at least one substituted light-sensitive group, and when irradiating polarized UV light having a wavelength of 150 to 450nm with a total light amount of less than or equal to 20mJ/cm2, the maximum value of the absolute value of d(dichloric ratio)/d(mJ/cm2), which is the amount of variation of the dichloric ratio per unit light amount (mJ/cm2), is at least 0.003.
(FR)La présente invention concerne un polymère photosensible et une couche d'alignement le comprenant, présentant une vitesse d'alignement et une stabilité d'alignement supérieures. Ledit polymère photosensible comprend une unité répétitive à base d'oléfines de type cyclique comprenant au moins un groupe photosensible substitué. Lors de l'irradiation d'une lumière UV polarisée présentant une longueur d'onde de 150 à 450 nm et une quantité totale de lumière inférieure ou égale à 20mJ/cm2, la valeur maximale de la valeur absolue de d(rapport dichroïque)/d(mJ/cm2), qui est la mesure de variation du rapport dichroïque par unité lumineuse (mJ/cm2), est supérieure ou égale à 0,003.
(KO)본 발명은 우수한 배향속도 및 배향 안정성을 나타내는 광반응성 중합체 및 이를 포함하는 배향막에 관한 것이다. 상기 광반웅성 중합체는 하나 이상의 광반웅기가 치환된 고리형 올레핀계 반복단위를 포함하고, 150 내지 450nm의 파장을 갖는 UV 편광을 20 mJ/cm2 이하의 총 광량으로 조사하였을 때, 단위 광량 (mJ/cm2)당 이방성 (dichloric ratio)의 변화량인 d(dichloric ratio)/d(mJ/cm2)의 절대값의 최대값이 0.003 이상인 것이다.
