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), a dispersion medium (B), and water (C). When a content of the light diffusion particle (A) is defined as Ma pts.mass and a content of the water (C) is defined as Mc pts.mass, the ratio between them, Ma/Mc, is 5-500.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、水（Ｃ）と、を含有する導光板用組成物であって、前記光拡散粒子（Ａ）の含有量をＭａ質量部、前記水（Ｃ）の含有量をＭｃ質量部としたときに、両者の比Ｍａ／Ｍｃが５〜５００であることを特徴とする。【選択図】図１
