Zusammenfassung:To provide a flexible optical laminate which is less susceptible to generation of air bubbles in moist heat environments and makes it difficult to see steps on an outer surface of a product.SOLUTION: A flexible optical laminate 100 provided herein comprises multiple optical members 110, 120 and a coloring layer 130, the multiple optical members 110, 120 being stacked via an adhesive layer 140, and is divided into a display area 101 and a non-display area 102 in a planar view. The coloring layer 130 is formed in the non-display area 102. A level difference between the display area 101 and the non-display area 102 is 1.2 μm or less on an outermost surface of the flexible optical laminate 100 on the viewer side.SELECTED DRAWING: Figure 2 【課題】湿熱環境下で気泡が生じにくく、製品の外側面の段差が視認されにくいフレキシブル光学積層体の提供。【解決手段】複数の光学部材110、120と、着色層130とを備えるフレキシブル光学積層体100であって、複数の光学部材110、120は粘着剤層140を介して積層され、平面視において表示領域101と非表示領域102とに区別され、着色層130は、非表示領域102に形成され、視認側の最外面において、表示領域101と非表示領域102との段差が1.2μm以下である、フレキシブル光学積層体100。【選択図】図2
