Zusammenfassung:A planar light source device includes: a substrate having a thickness larger than 0.9 mm and including a metal layer; and a plurality of light-emitting diode chips disposed on the substrate in a matrix array. Each light-emitting diode chip has a chip size ranging from 0.0784 mm2 to 0.25 mm2. Two adjacent ones of the light-emitting diode chips are spaced apart from each other by a distance of at least two times a length of the light-emitting diode chips.
