    Abstract: A light emitting device includes a mounting board, a light emitting element, first and second light reflecting members, a light transmissive member and a sealing member. The first light reflecting member surrounds a lateral surface of the light emitting element while a top surface of the light emitting element is exposed from the first light reflecting member. The second light reflecting member surrounds an outer periphery of the light emitting element in a plan view. The second light reflecting member is in contact with the first light reflecting member with at least a part of the second light reflecting member being positioned higher than the first light reflecting member. The light transmissive member is disposed inside the second light reflecting member. The light transmissive member includes a wavelength conversion substance. The sealing member covers the first and second light reflecting members and the light transmissive member.

    Abstract: A light-emitting device includes light-emitting elements each having a light-extracting surface, light-transmissive members and a covering member, The light-transmissive members each has an upper surface and a lower surface facing the light-extracting surface of at least one of the light-emitting elements. The covering member integrally covers lateral surfaces of the light-emitting elements and lateral surfaces of the light-transmissive members such that a pair of electrodes of the light-emitting elements are exposed from the covering member at a lower surface of the covering member. At a lower surface of the light-emitting device, the light-emitting elements are arranged in a plurality of columns and a plurality of rows, an alignment direction of the electrodes in one of the light-emitting elements is rotated by 90° in a prescribed. direction from an alignment direction of the electrodes in an adjacent one of the light-emitting elements in one of a column direction and a row direction.

    Abstract: A light emitting device includes a supporting base member which has an external electrode, at least one light emitting element disposed on at least a portion of an upper surface of the supporting base member. A sealing member encloses the light emitting element and has an outermost periphery larger than the supporting base member in a plan view. The supporting base member has at least one recess. The sealing member is filled in at least a portion of the recess and is formed so as to expose an electrode surface of the external electrode.
