PROBLEM TO BE SOLVED: To provide a deflection plate integrated optical laminate capable of being a thin film, at the same time, having a display screen of the image display device be flat, preventing occurrence of a curl by suppressing a dimension change due to temperature change and suppressing a change in hue, even when viewed with a pair of sunglasses having a deflection property.SOLUTION: A deflection plate integrated optical laminate 10 is arranged on a display screen side of an image display panel and the optical laminate is laminated on a deflection element film 11. In this case, the optical laminate includes a photo-transmissive base material 12 having birefringence in a screen and a bar code layer 14 provided on a shield layer 13. The phot-transmissive base material 12 has retardation of 3000nm or more and the photo-transmissive base material 12 on the optical laminate is provided on the deflection element film 11. |
