description To provide an optical laminate for use in an OLED display device which does not use polarizing plates and is less susceptible to image blur even when a light scattering layer is laminated to suppress color shift and interference unevenness appearing when viewed from oblique directions.SOLUTION: The present invention provides an optical laminate for use in an OLED display device having just an optical element with a polarization degree of 95% or less laminated on an OLED element on a viewer side. The OLED display device has a color filter disposed on the viewer side of the OLED element. Only the optical element is laminated on the viewer side of the color filter. The optical element has at least adhesive layers and at least one of the adhesive layers has a light scattering property. A distance d between the adhesive layer having the light scattering property and the color filter is 700 μm or less.SELECTED DRAWING: Figure 4 【課題】偏光板を使用しないOLED表示装置において、斜め方向から見た場合に生じるカラーシフトや、干渉ムラを抑制するために光散乱層を積層しても、画像ボケが生じにくいOLED表示装置に用いられる光学積層体を提供すること。【解決手段】本発明は、OLED素子の視認側に偏光度95%以下の光学素子のみが積層されたOLED表示装置に用いられる光学積層体を提供する。前記OLED表示装置は、OLED素子の視認側にカラーフィルタが配置されている。前記カラーフィルタの視認側には、前記光学素子のみが積層されている。前記光学素子は、少なくとも粘着剤層を有し、前記粘着剤層の少なくとも1層は、光散乱特性を有している。前記光散乱特性を有する粘着剤層と、前記カラーフィルタとの間の距離dは700μm以下である。【選択図】図4
