1. A light emitting device comprising:
a first light transmissive support including a first light transmissive insulator and a first conductive circuit layer provided on a first surface of the first light transmissive insulator; a second light transmissive support including a second light transmissive insulator and a second conductive circuit layer provided on a second surface of the second light transmissive insulator opposed to the first surface; a plurality of light emitting diodes, arranged between the first light transmissive insulator and the second light transmissive insulator so that a minimum distance d is 500 μm or more, each including a first electrode electrically connecting to the first conductive circuit layer, and a second electrode electrically connecting to the second conductive circuit layer; and a third light transmissive insulator embedded between the first light transmissive insulator and the second light transmissive insulator, wherein the third light transmissive insulator has a minimum thickness T2 between the plural light emitting diodes, which is smaller than a height T1 of the light emitting diode by a range of 5 μm or more and ½ or less of the height T1, and wherein a difference ΔT (T1−T2) between the height T1 of the light emitting diode and the minimum thickness T2 of the third light transmissive insulator falls within a range surrounded by a straight line 1 expressed by ΔT=5, a straight line 2 expressed by d=500, a straight line 3 expressed by ΔT=0.09d, a straight line 4 expressed by ΔT=0.0267d+60, and a straight line 5 expressed by ΔT=½ T1, in a graph with the difference ΔT [unit:μm] plotted on a vertical axis and the minimum distance d [unit:μm] between the plural light emitting diodes plotted on a horizontal axis. |
