Abstract
Provided is a light source device including: a housing body; a light source substrate located over and accommodated in the housing body; a plurality of inorganic light-emitting elements over the light source substrate; an optical sheet located over the plurality of inorganic light-emitting elements, accommodated in the housing body, and spaced away from the light source substrate; and at least one spacer accommodated in the housing body and in contact with a bottom surface of the optical sheet. A region of an upper surface of the light source substrate overlapping the plurality of inorganic light-emitting elements does not overlap the at least one spacer.

A light source device comprising:
- a housing body;
- a light source substrate located over and accommodated in the housing body;
- a plurality of inorganic light-emitting elements over the light source substrate;
- an optical sheet located over the plurality of inorganic light-emitting elements, accommodated in the housing body, and spaced away from the light source substrate;
- and
- at least one spacer accommodated in the housing body and in direct contact with a bottom surface of the optical sheet,
- wherein a first region of an upper surface of the light source substrate overlaps all of the plurality of inorganic light-emitting elements, and a second region of an upper surface of the light source substrate outside the first region overlaps the at least one spacer,
- the at least one spacer includes:
- a first supporting layer;
- and
- a second supporting layer over and in contact with the first supporting layer, and the first supporting layer and the second supporting layer respectively include a first material and a second material different from each other.
A light source device comprising:
- a housing body;
