    Abstract: A light emitting device includes a resin package including a first lead and a second lead. A light emitting element includes a first electrode disposed to face the first lead and having a first post electrode projecting toward the first lead in a first projecting direction with a height equal to or larger than 50 μm and equal to or smaller than 150 μm in the first projecting direction and a second electrode disposed to face the second lead and having a second post electrode projecting toward the second lead in a second projecting direction with a height equal to or larger than 50 μm and equal to or smaller than 150 μm in the second projecting direction. A first electrically conductive bonding member connects the first lead and the first post electrode. A second electrically conductive bonding member connects the second lead and the second post electrode.

    Abstract: A light emitting device including a molded package having leads including a pair of a first lead and a second lead, a molded resin, and a recess, where an upper surface of the leads is partially exposed from a bottom surface of the recess. The device further including a light emitting component mounted on the bottom surface, and at least one sealing member located in the recess to cover the light emitting component. At least one of the first lead and the second lead has a groove on an upper surface thereof, where the groove is positioned so as to correspond to a corner on the bottom surface of the recess in a cross sectional view. A portion of the molded resin located within the groove is exposed from the bottom surface. A surface of the corner is composed of a curved surface, and the sealing member covers the corner.

    IPC: G02F1/13357

    CPC classification number: G02F1/133603

    Abstract: A planar light source has a plurality of light sources, a substrate, and a partitioning member. The partitioning member includes a first member provided with first partitioned parts each having a first bottom part and first oblique parts surrounding the first bottom part that are arranged on the substrate in a matrix, and a second member provided with second partitioned parts each having a second bottom part and second oblique parts surrounding the second bottom part that are arranged on the substrate in a matrix. The first member further has first outer oblique parts overlapping the second oblique parts located along the outer edge of the second member on the first member side. The first bottom parts and the second bottom parts each have a light source disposition opening, and the light sources are individually disposed on the substrate exposed in the light source disposition openings.
