Beschreibung
Zusammenfassung:	One embodiment of the present invention is to provide: a photosensitive composition which includes a cardo-based compound with three or more reactive groups in a cardo-based core with many aryl groups, so that high photosensitivity is achieved, and phenomena such as undercutting at the bottom of the pattern do not occur during the development stage, resulting in a high-resolution and highly reliable cured pattern; and an organic light emitting display device using the same. 본 발명의 일 실시예는 아릴기가 많은 카도계 코어에 반응기가 3개 이상 있는 카도계 화합물을 포함함으로써, 높은 광감도를 갖게 되고, 현상 단계에서 패턴 하부 언더컷과 같은 현상이 일어나지 않아서 높은 해상도 및 높은 신뢰성의 경화 패턴이 구현되는 감광성 조성물 및 이를 적용한 유기발광 표시장치를 제공하기 위한 것이다.
