A manufacturing method of a symbol button for a vehicle includes: preparing a button body comprising a side portion, a top portion formed of a polymer material on which a metal is able to be plated; forming an electrically conductive layer on an outside of the button body using a conductive polymer material; forming a plating shielding layer in a form of a symbol using a material on which a metal is not able to be plated on the electrically conductive layer; and performing metal plating on the outside of the button body having the plating shielding layer.

Provided is a light-diffusing barrier film. The film is an integral film comprising a barrier layer, a base layer and a light-diffusing layer, sequentially. The film can prevent moisture penetration into a device such as an organic light emitting device, and also imparts a light-diffusing function to the device. In particular, the film can have excellent moisture blocking properties even after a roll-to-roll process.
