Abstract
A light emitting device of the disclosure includes a first light source and a second light source; a light-guiding plate having a first main surface and a second main surface that face each other, a first end surface facing the first light source, and a second end surface facing the first end surface and the second light source; a prism sheet disposed to face the first main surface; and a reflection sheet disposed to face the second main surface. The light-guiding plate includes a plurality of first slope sections and a plurality of second slope sections both provided on one of the first main surface and the second main surface, in which the plurality of first slope sections are provided to allow the light-guiding plate to be thinner in a first direction that extends from the first end surface to the second end surface, and the plurality of second slope sections are provided to allow the light-guiding plate to be thicker in the first direction, and each provided alternately with each of the first slope sections in the first direction. A proportion of area occupied by the second slope sections increases in a predetermined range from the second end surface, as a distance from the second end surface increases.
