Abstract:
A method for producing a light emitting transfer sheet includes the steps of preparing a light emitting element sheet including a light semiconductor layer connected to an electrode portion on one side surface and a phosphor layer laminated on the other side surface; dividing the light emitting element sheet into plural pieces to form a plurality of light emitting elements; disposing a plurality of the light emitting elements on a substrate to be spaced apart from each other; forming a reflecting resin layer containing a light reflecting component on the substrate so as to cover the light emitting elements; and removing the reflecting resin layer partially so that one side surface of the electrode portion is exposed from the reflecting resin layer.
