Abstract: The present invention relates to a light-diffusing ink composition and to a light guide panel and display unit using same, wherein the light-diffusing ink composition comprises: an ink binder made of one or more selected from a group consisting of acrylic resin and polyvinyl chloride (PVC) copolymer; polymethylmethacrylate (PMMA) particles for forming a crystal optical pattern; and a solvent for ink. According to the present invention, light from a light source is converted into a crystal optical pattern and outputted, thus producing aesthetic and sensuous light, and lighting with an aesthetic design can be achieved by means of the light guide panel using the composition.
