PROBLEM TO BE SOLVED: To provide a composition for light guide plates that makes it possible to prepare a light guide plate that allows light to be emitted homogeneously from the light emission surface side with improved brightness, and also has excellent storage stability.SOLUTION: A composition for light guide plates comprises a light diffusion particle (A) and a dispersion medium (B). When the composition is used to prepare a cured film of 10 μm in thickness, the cured film has a reflectance of 0-50% at wavelengths of 300-380 nm and a reflectance of 30-99% at wavelengths of 400-800 nm.SELECTED DRAWING: Figure 1 【課題】光をより高い輝度で光出射面側に均質に出射できる導光板を作製することができ、かつ、保存安定性にも優れる導光板用組成物を提供する。【解決手段】本発明に係る導光板用組成物は、光拡散粒子（Ａ）と、分散媒体（Ｂ）とを含有する導光板用組成物であって、前記組成物を用いて作製された厚さ１０μｍ硬化膜の、波長３００〜３８０ｎｍにおける反射率が０〜５０％であり、波長４００〜８００ｎｍにおける反射率が３０〜９９％であることを特徴とする。【選択図】図１
