| Zusammenfassung: | To provide an optical laminate with an adhesive layer and a display device capable of excellently adhering the side surface of a through hole and a filling material even when the filling material is filled in the through hole.SOLUTION: An optical laminate with an adhesive layer includes: an optical laminate including a polarizing plate having a protective layer on at least one side of a linear polarizing layer; an adhesive layer provided on one side of the optical laminate; and a through-hole penetrating in the laminating direction. The thickness of the linear polarizing layer is 10 μm or less. The maximum height Sa of the side surface of the optical laminate portion among the side surfaces of the through hole is 2.0 μm or less.SELECTED DRAWING: Figure 2
【課題】貫通孔に充填材料を充填した場合にも、貫通孔の側面と充填材料とを良好に密着することができる粘着剤層付き光学積層体及び表示装置を提供する。【解決手段】粘着剤層付き光学積層体は、直線偏光層の少なくとも片面に保護層を有する偏光板を含む光学積層体と、光学積層体の片面に設けられた粘着剤層と、を有し、積層方向に貫通する貫通孔を有する。直線偏光層の厚みは、１０μｍ以下である。貫通孔の側面のうちの光学積層体部分の側面の最大高さＳａは、２．０μｍ以下である。【選択図】図２ |
