Abstract
A light emitting device includes: a lightguide plate including a first surface on which a plurality of first recesses are provided; a light-reflective resin layer located on a bottom portion of each first recess; a plurality of light emitting elements each having an upper surface and a lateral surface, wherein each one of the plurality of light emitting elements is arranged in a corresponding one of the plurality of first recesses; and a plurality of wavelength conversion members, wherein: the upper surface of each light emitting element is attached to the light-reflective resin layer; and each of the plurality of wavelength conversion members covers the lateral surface of the light emitting element in the first recess.
Claims7
A light emitting device comprising:
- a lightguide plate including a first surface on which a plurality of first recesses are provided, and a second surface located on an opposite side from the first surface;
- a plurality of light emitting elements each having an upper surface and a lateral surface, wherein each one of the plurality of light emitting elements is arranged in a corresponding one of the plurality of first recesses, with the upper surface facing a bottom portion of the first recess;
- and
- a plurality of wavelength conversion members, wherein:
- each light emitting element includes a reflective film on a side of the upper surface;
- and
- each of the plurality of wavelength conversion members covers the upper surface and the lateral surface of the light emitting element in the first recess,
- wherein:
- each of the plurality of light emitting elements includes an electrode provided on an opposite side from the upper surface;
- the light emitting device further includes a light-reflective member that is located on a side of the first surface of the lightguide plate and covers an area excluding the electrode;
- the lightguide plate has a rectangular outer shape as seen in a plan view;
- an outer shape of each first recess as seen in a plan view is a rectangular shape;
- and
- each side of the rectangular outer shape of each first recess is generally parallel to a diagonal line of the rectangular outer shape of the lightguide plate.
