Abstract
To provide a light guide plate for image display in which the visual field angle is improved while securing the optical characteristics such as the light transmissivity and transparency.SOLUTION: There is provided a light guide plate 1 for image display which is made of a laminate including at least a hologram layer 10, a first resin substrate 11 and a high refraction layer 13. The hologram layer 10 is arranged on one side in the thickness direction of the first resin substrate 11 or the high refraction layer 13. The high refraction layer 13 is arranged on the at least one side in the thickness direction of the first resin substrate 11. The total of the thicknesses of the first resin substrate 11 and the high refraction layer 13 is between 0.01 mm and 3 mm. The ratio of the thickness of the first resin substrate 11 is 10-99.9% and the ratio of the thickness of the high refraction layer 13 is 0.1-90%.SELECTED DRAWING: Figure 1
