Abstract
Official abstract text for this publication.
A method for manufacturing a light-emitting device includes providing a soluble member to cover at least one lateral surface of a light-emitting element. The soluble member includes a material soluble in a first solvent. A light-shielding member is provided to cover at least one lateral surface of the soluble member. The light-shielding member includes a light-shielding resin less soluble in the first solvent than the soluble member. The soluble member is removed with the first solvent. A first light-transmissive member is provided in a space formed by removing the soluble member.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for manufacturing a light-emitting device, the method comprising: providing a soluble member to cover at least one lateral surface of a light-emitting element, the soluble member comprising a material soluble in a first solvent; providing a light-shielding member to cover at least one lateral surface of the soluble member, the light-shielding member comprising a light-shielding resin less soluble in the first solvent than the soluble member; removing the soluble member with the first solvent; and providing a first light-transmissive member in a space formed by removing the soluble member. 2 . The method according to claim 1 , wherein the soluble member further covers an upper surface of the light-emitting element. 3 . The method according to claim 2 , the method further comprising: forming a second light-transmissive member on an upper surface of the light-emitting element. 4 . The method according to claim 2 , wherein at least one of the first light-transmissive member and the second light-transmissive member comprises a wavelength conversion substance. 5 . The method according to claim 4 , wherein a slurry including a liquid resin having the wavelength conversion substance is dropped into the space formed by removing the soluble member to form the first light-transmissive member. 6 . The method according to claim 5 , wherein the slurry is cured to form the first light-transmissive member after the wavelength conversion substance settles down. 7 . The method according to claim 1 , wherein the first solvent is water or a ketone-based organic solvent such as acetone and methyl ethyl ketone.
