Beschreibung
Zusammenfassung:	An object of the present invention is to provide an optical laminated body in which frame-like display defects are suppressed. The optical laminated body according to an embodiment of the present invention comprises a front plate, an adhesive layer, a polarizing plate, and a phase difference layer in sequence. The polarizing plate includes a polarizing element and a protective layer configured on the adhesive layer side of the polarizing element. The adhesive layer includes a photo-curable adhesive containing a compound having a maximum absorption wavelength of 200 nm to 300 nm. The single-body transmittance of the polarizing element is 43.3% or more. Alternatively, the moisture permeability of the protective layer is 100 g/cm2*24 hr or less.
