PURPOSE: A high brightness micro array light emitting diode device is provided to maximize light extraction efficiency by optimizing the size, interval, etching angle, and etching depth of a unit device. CONSTITUTION: A plurality of triangular micro arrays is located on a substrate. The outer diameter(120) of the micro array is 7 to 9 um. An interval(130) between the micro arrays is 3 um. The etching depth(140) of the micro array is 2.5 to 3.5 um. The etching angle(150) of the micro array is 60 degrees.
