Abstract
A growth substrate including micro-light emitting diode (LED) chips and a method of manufacturing a light emitting diode display using the growth substrate are disclosed. The growth substrate includes LED chips. The LED chips are divided into n groups each including p LED chips, where each of the n and p is an integer equal to or greater than 2. At least two of the n groups are adjacent to each other. Each of the n includes a first LED chip having a directionality toward a first direction and a second LED chip having a directionality toward a second direction different from the first direction.
