LENS MANUFACTURING METHOD

To provide a novel method for manufacturing a lens using a photocurable resin composition.SOLUTION: A method for manufacturing a lens of a convex shape which is composed of a cured product of a photocurable resin composition on a substrate includes a photocurable resin composition layer formation step of applying the photocurable resin composition onto the substrate, and forming a photocurable resin composition layer, an exposure step of selectively exposing the photocurable resin composition layer, and a step of developing the photocurable resin composition layer after the exposure step, wherein in the exposure step, the photocurable resin composition layer is exposed with an exposure amount of 2.0 or more folds of a saturation exposure amount.SELECTED DRAWING: Figure 1 【課題】光硬化性樹脂組成物を用いてレンズを製造する新規な方法を提供することを目的とする。【解決手段】基板の上に光硬化性樹脂組成物の硬化物からなる凸面形状のレンズを製造する方法であって、前記光硬化性樹脂組成物を前記基板の上に塗布して光硬化性樹脂組成物層を形成する光硬化性樹脂組成物層形成工程と、前記光硬化性樹脂組成物層を選択的に露光する露光工程と、前記露光工程の後に、前記光硬化性樹脂組成物層を現像する工程と、を有し、前記露光工程において、前記光硬化性樹脂組成物層を飽和露光量の２．０倍量以上の露光量で露光する、方法。【選択図】図１
