Provided is a composition for a light guide plate, which can manufacture a light guide plate capable of uniformly emitting light with a higher luminance to a light emission surface side and has excellent storage stability. The composition for a light guide plate according to the present invention comprises: light diffusion particles (A); and a dispersion medium (B), wherein reflectance in 300 to 380 nm wavelength of a cured film with 10 m thickness manufactured by using the composition is 0 to 50% and reflectance in 400 to 800 nm wavelength of the cured film with 10 m thickness manufactured by using the composition is 30 to 99%. (과제) 빛을 보다 높은 휘도로 광 출사면측에 균질하게 출사할 수 있는 도광판을 제작할 수 있고, 또한, 보존 안정성도 우수한 도광판용 조성물을 제공한다. (해결 수단) 본 발명에 따른 도광판용 조성물은, 광 확산 입자(A)와, 분산 매체(B)를 함유하는 도광판용 조성물로서, 상기 조성물을 이용하여 제작된 두께 10㎛ 경화막의, 파장 300∼380㎚에 있어서의 반사율이 0∼50％이고, 파장 400∼800㎚에 있어서의 반사율이 30∼99％인 것을 특징으로 한다.
