An optical resin sheet includes a cured resin layer containing glass fiber, wherein the ratio of the elastic modulus of the glass fiber to the elastic modulus of a cured resin material, which forms the cured resin layer, is 25 or more. With the thus arranged optical resin sheet, stress is applied to the glass fiber, thereby reducing the phenomenon of occurrence of birefringence, and when it is applied to a display device, there is achieved a significantly small light leakage in an oblique direction. The optical resin sheet is capable of achieving excellent display quality of an image display device such as a liquid crystal display device, as well as keeping the coefficient of thermal expansion lower and the mechanical strength higher.
