Abstract
A method of manufacturing a planar light source includes disposing a plurality of light emitting devices on a substrate and disposing an optical sheet to be separated from the light emission surface formed by the plurality of light emitting devices by an optical length l, the step of disposing the plurality of light emitting devices on the substrate including determining a degree of pitch S between two adjacent light emitting devices among the plurality of light emitting devices, and the step of determining the degree of pitch S including: calculating a degree of luminance of the light emitting device in the optical sheet, and determining a distance between one region in the optical sheet directly above the light emitting device, and another region in the optical sheet having a half of maximum luminance, to be S/2.
