1. A light emitting device comprising:
at least one light emitting element including a light-extracting surface and at least one lateral surface;
a wavelength converting member comprising;
a first upper surface and a second upper surface,
a lower surface located at an opposite side from the first upper surface and the second upper surface,
at least one first lateral surface connecting the second upper surface and the first upper surface, and
at least one second lateral surface directly contacting and connecting the second upper surface and the lower surface, wherein
a first thickness between the lower surface and the first upper surface is smaller than a second thickness between the lower surface and the second upper surface, and
the first upper surface is located at an opposite side from the light-extracting surface of a corresponding one of the at least one light emitting element, and the lower surface is located facing the light-extracting surface of the corresponding one of the at least one light emitting element;
a covering member covering the at least one second lateral surface of the wavelength converting member and the at least one lateral surface of the at least one light emitting element; and
a light-shielding film covering the second upper surface of the wavelength converting member.
