Abstract
A surface light source device includes a plurality of light source blocks, each of which includes a light-emitting element array composed of a plurality of light-emitting elements arranged in the first direction. Each of the plurality of light-emitting elements includes a plurality of light emission chips arranged in the first direction, with different colors of emission light. In the light-emitting element array, the colors of the light emitted from the light emission chips at both end portions are the same.
Claims17
A surface light source device comprising a plurality of light source blocks arranged in a first direction and a second direction orthogonal to the first direction,
- wherein each of the plurality of light source blocks includes one or more lines of a light-emitting element array including a plurality of light-emitting elements arranged in the first direction;
- wherein each of the plurality of light-emitting elements includes a plurality of light emission chips arranged in the first direction, the plurality of light emission chips being different from each other in color of emission light;
- wherein in the one or more lines of the light-emitting element array in the light source block, colors of light emitted from all of the light emission chips at both end portions are the same;
- and
- wherein in plan view, each pair of adjacent ones of the light-emitting elements in the light emitting element array is disposed such that colors of light emitted from the light emission chips are line-symmetric with respect to a boundary between the adjacent light-emitting elements.
