The present invention provides a light guide plate capable of emitting light from a light-emitting surface at a higher luminance, a surface light source device and a transmission-type image display device having the light guide plate, a light guide plate manufacturing method, and a UV curable inkjet ink for the light guide plate. A light guide plate includes: a transparent resin sheet having a light-emitting surface that emits light incident from an end face and having a rear face on the opposite side of the light-emitting surface; and a plurality of reflective dots provided on the rear face of the transparent resin sheet and formed by photo-curing of dot-shaped ink. The ink contains a pigment, a photopolymerizable component, and a photopolymerization initiator. In addition, the rear face is a liquid repellent-treated surface.
