Zusammenfassung:	To provide an optical laminate for use in an OLED display device which does not use polarizing plates and offers superior shock resistance.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 a transparent polyimide layer and a hard coat layer.SELECTED DRAWING: Figure 17 【課題】偏光板を使用しないＯＬＥＤ表示装置において、耐衝撃性に優れる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、少なくとも透明ポリイミド層及びハードコート層を有する。【選択図】図１７
