Planar light-emitting device

The planar light-emitting device comprising:

• a linear light-emitter comprising:
• a substrate extending in a predetermined direction,
• a first line and a second line including a plurality of light-emitting elements arranged along the predetermined direction on the substrate, the first line and the second line being arranged side by site along the predetermined direction with an interval;
• a first seal sealing the first line of the plurality of light-emitting elements;
• a second seal sealing the second line of the plurality of light-emitting elements;
• a first seal arranged inside the first frame for sealing the plurality of light-emitting elements;
• a second seal arranged inside the second frame for sealing the plurality of light-emitting elements;
• a first seal arranged inside the first frame for sealing the plurality of light-emitting elements;
• a second seal arranged inside the second frame for sealing the plurality of light-emitting elements;
• and
• a plurality of electrodes arranged on the substrate and electrically connected with the plurality of light-emitting elements;
• and
• a light guide plate having an incidence surface having a first flat portion facing to the first line, a second flat portion facing to the second line, a projecting portion arranged between the first flat portion and the second flat portion and projecting toward the linear light-emitter, and an emission surface that emits light incident from the incidence surface, wherein
• the projecting portion has a first light-incoming surface arranged at an angle so as to face to an end portion of the first frame on the second frame side, and a second light-incoming surface arranged at an angle so as to face to an end portion of the second frame on the first frame side.
