The present invention relates to a photosensitive resin composition, a color filter manufactured using the same, and a display device comprising the same. The photosensitive resin composition according to the present invention comprises a photopolymerization initiator and has a wavelength of 350-390 nm, among a region (A) defined by a normalized emission spectrum of an exposure machine, a region (P) defined by an absorption spectrum of a photopolymerization initiator, and a region (B) defined by an overlapped region of the region (A) and the region (P), the area ratio of the region (B) to the region (A) is 0.4 or more. 본 발명은, 350 내지 390nm 파장에 대하여, 노광기의 정규화된 발광 스펙트럼에 의해 정의되는 영역(A); 광중합 개시제의 흡광 스펙트럼에 의해 정의되는 영역(P); 및 상기 영역(A) 및 영역(P)의 중첩되는 영역으로 정의되는 영역(B)에 있어서, 영역(A)에 대한 영역(B)의 면적비가 0.4 이상인 광중합 개시제를 포함하는, 감광성 수지 조성물, 이를 이용하여 제조된 컬러필터 및 이를 포함하는 표시장치에 관한 것이다.
