OPTICAL LAMINATE AND IMAGE DISPLAY DEVICE USING THE SAME

The invention provides an optical laminate and an image display device using the same. [Problem] To provide an optical laminate in which frame-shaped display defects are suppressed. [Solution] An optical laminate according to an embodiment of the present invention has a front panel, an adhesive layer, a polarizing plate, and a phase difference layer in this order. The polarizing plate includes a polarizer and a protective layer disposed on the adhesive layer side of the polarizer. The pressure-sensitive adhesive layer is configured from a photocurable pressure-sensitive adhesive containing a compound having an absorption maximum wavelength of 200-300 nm. The polarizer has a single transmittance of less than 43.3% and an orthogonal absorbance A210 of 0.60 or less at an average thickness of 1 [mu] m at a wavelength of 210 nm. 一种光学层叠体和使用该光学层叠体的图像显示装置。[课题]提供框状显示缺陷受到抑制的光学层叠体。[解决手段]本发明的实施方式所述的光学层叠体依次具有前面板、粘合剂层、偏光板和相位差层。偏光板包含偏光件和保护层，所述保护层配置在偏光件的粘合剂层侧。粘合剂层由包含吸收极大波长为200nm～300nm的化合物的光固化性粘合剂构成。偏光件的单片透射率小于43.3％，且波长210nm下
