Summary:To provide a sealing film that is difficult to cause degradation of the antireflection performance when combined with an antireflection film provided with circular polarization, is excellent in the handling property, and is capable of excellently sealing.SOLUTION: A sealing film 100 is a sealing film 100 including : a base film 110; a sealing layer 120; and an adhesive layer 130 formed with a resin, in this order, in which the sealing film 100 has the tensile elasticity of 1000 MPa or larger, the tensile elasticity of the adhesive layer 130 is 1500 MPa or smaller, and when sealed at a sealing temperature of Tg+10°C or higher and Tg+150°C or lower (Tg represents a highest glass transition temperature of a resin forming the adhesive layer 130), the retardation of a layer part provided on the sealing layer 120 side than the base film 110 of the sealing film 100 after sealing is 20 nm or smaller.SELECTED DRAWING: Figure 1 【課題】円偏光板を備えた反射防止フィルムと組み合わせた場合に反射防止性能の低下を招き難く、ハンドリング性に優れ、良好な封止が可能な封止フィルムの提供。【解決手段】基材フィルム１１０、封止層１２０及び樹脂で形成された接着性層１３０をこの順に備える封止フィルム１００であって、封止フィルム１００が、１０００ＭＰａ以上の引張り弾性率を有し、接着性層１３０の引張り弾性率が、１５００ＭＰａ以下であり、Ｔｇ＋１０℃以上Ｔｇ＋１５０℃以下の封止温度（Ｔｇは、接着性層１３０を形成する樹脂の最も高温のガラス転移温度を表す。）で封止したときの、封止後における封止フィルム１００の基材フィルム１１０よりも封止層１２０側に設けられた層部分のレターデーションが、２０ｎｍ以下である、封止フィルム１００。【選択図】図１
