Zusammenfassung: | To provide a novel optical laminate capable of suppressing color loss at edges of a polarizer under high temperature and high humidity.SOLUTION: An optical laminate 100 provided herein comprises a polarizer 10, a selective light absorbing adhesive layer 20, and an intermediate layer 300 laminated between the polarizer and the selective light absorbing adhesive layer in contact therewith. The intermediate layer has just one or more layers selected from a group consisting of a liquid crystal cured layer, alignment layer, and adhesive layer. The polarizer has iodine absorbed and aligned therein and contains 5.0 mass% or less boron. The selective light absorbing adhesive layer contains a selective light absorber, and exhibits an absorbance in a range of 0.1 to 2.3, inclusive, at a wavelength of 410 nm.SELECTED DRAWING: Figure 1
