US 2019/0165218 A1 · LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURING SAME

Abstract

A light emitting device includes: a substrate; a light emitting element disposed on the substrate; a light transmissive member having a plate shape and having an upper face and a lower face disposed such that the lower face opposes a light emission face of the light emitting element; a light reflecting member covering lateral faces of the light emitting element and lateral faces of the light transmissive member; and a light shielding frame disposed on the upper face of the light reflecting member surrounding the light transmissive member. The light shielding frame has an opening, an inner perimeter of the opening is positioned at a distance apart from an outer perimeter of the upper face of the light transmissive member in a plan view as seen from above, and the light reflecting member is interposed between the inner perimeter of the opening and the outer perimeter of the upper face of the light transmissive member.

A light emitting device comprising:

a substrate;
a light emitting element disposed on the substrate;
a light transmissive member having a plate shape and having an upper face and a lower face disposed such that the lower face opposes a light emission face of the light emitting element;
a light reflecting member covering lateral faces of the light emitting element and lateral faces of the light transmissive member;
and
a light shielding frame disposed on the upper face of the light reflecting member surrounding the light transmissive member;
wherein the light shielding frame has an opening, an inner perimeter of the opening is positioned at a distance apart from an outer perimeter of the upper face of the light transmissive member in a plan view as seen from above, and the light reflecting member is interposed between the inner perimeter of the opening and the outer perimeter of the upper face of the light transmissive member.

A method of manufacturing a light emitting device, the method comprising:

mounting a light emitting element on a substrate, bonding a light transmissive member having a plate shape such that a lower face of the light transmissive member faces a light emission face of the mounted light emitting element;
forming a resin wall having upper end higher than an upper face of the light transmissive member in locations at a predetermined distance apart from the light emitting element and the light transmissive member and interposed by the light emitting element and the light transmissive member while being deformable by a pressing force;
disposing a light shielding frame having an opening at a predetermined height from the substrate by pressing the light shielding frame to be in contact with the upper end of the resin wall such that an inner perimeter of the opening is positioned on or outward of the outer perimeter of the upper face of the light transmissive member;
and
forming a light reflecting member that surrounds the light emitting element and the light transmissive member between the substrate and the light shielding frame by supplying a light reflecting resin into a space between the substrate and the light shielding frame.
