Zusammenfassung:	To provide an optical laminate for use in an OLED display device which does not use polarizing plates and offers suppressed 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 optical element has at least adhesive layers and at least one of the adhesive layers has a light scattering property.SELECTED DRAWING: Figure 3 【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、干渉ムラが抑制された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。【選択図】図３
