An optical device producing method includes: Step A of forming a wall portion surrounding an application region for a photocurable resin composition on an optical member or a transparent panel; Step B of applying a photocurable resin composition to the application region; Step C of forming a laminate by laminating the optical member and the transparent panel via the photocurable resin composition under a reduced-pressure atmosphere lower than atmospheric pressure; and Step D of removing babbles in the photocurable resin composition by pressurizing the laminate. In Step B, at least the height of the photocurable resin composition on the side of the wall portion is made higher than the height of the wall portion, and the photocurable resin composition is applied so that the laminate formed in Step C has a plurality of separated spaces separated by bubbles formed in the thickness direction of the photocurable resin composition.

Optical device production method

Provided is a method for manufacturing an optical device capable of surely curing a photocurable resin composition. The method for manufacturing an optical devicein which an optical memberand a transparent panelare bonded together via a cured resin layerincludes: a step of forming, on one of the optical memberand the transparent panel, a wallsurrounding a forming region for the cured resin layerand having at least one opening; a step of laminating the optical memberand the transparent panelto form a laminated bodyin which a resin filling spacesurrounded by the wallis formed between the optical memberand the transparent panel; a step of filling the resin filling spaceof the laminated bodywith a photocurable resin composition; and a step of curing the photocurable resin compositionto form the cured resin layer

Optical device and method for manufacturing optical device

Provide is a method for manufacturing an optical device capable of filling a curable resin composition without protrusion to the periphery even in a manufacturing process of the optical device using a transparent panel having a curved surface shape. The method includes: filling a lamination side of a transparent panel having a curved surface shape with a curable resin composition, curing the curable resin composition filling the lamination side to form a first cured resin layer, forming a dam member on an optical member, laminating the transparent panel and the optical member to form a laminate having a resin filling space surrounded by the dam member, filling the resin filling space with the curable resin composition, precuring the curable resin composition filled in the resin filling space to form a precured resin layer, and final curing the precured resin layer.

Method for manufacturing optical device

Provided are a method for manufacturing a transparent panel formed with a wall member having high accuracy, a uniform height from a surface to adhere to an optical member, and smoothness. This method comprises: a step of preparing a transparent panelfor an optical deviceto be bonded to an optical membera step of forming a mask layerso as to form an openingalong a periphery of an outer shape of the transparent panela step of applying a curable resin materialto the openingand the mask layera step of pressing a flat plateagainst the curable resin materiala step of curing the resin compositionto form a cured resin layera step of detaching the flat plateand a step of removing the mask layertogether with the cured resin layerformed on the mask layerto obtain a wall memberalong the periphery of the outer shape of the transparent panel
