Title:
発光装置の製造方法及び発光装置
Document Type and Number:
Japanese Patent JP5892160
Kind Code:
B2
Abstract:
Provided are a method for producing a light-emitting device and a light emitting device which can effectively minimize color irregularities, and which is highly reliable, being devoid of resin separation. The method for producing a light-emitting device is a method for producing a light-emitting device having a light-emitting element, and a phosphor layer that absorbs at least some of the light output by the light-emitting element and emits light of a different wavelength than the absorbed light, wherein the method includes: a first resin layer formation step in which a first resin layer that defines a predetermined shape for a phosphor layer is formed on the light-emitting surface of the light-emitting element by a first resin that has been adjusted to a first viscosity; a second resin layer formation step in which, prior to curing of the first resin layer, a second resin layer is formed over the first resin layer, using a second resin that includes a phosphor and that has been adjusted to a second viscosity lower than the first viscosity; and a curing step in which the first resin layer and the second resin layer are cured.
