Abstract

A light emitting diode (LED) stack for a display including a first LED stack including a first conductivity-type semiconductor layer and a second conductivity-type semiconductor layer, a second LED stack disposed on the first LED stack, a third LED stack disposed on the second LED stack, an intermediate bonding layer disposed between the first LED stack and the second LED stack to bond the second LED stack to the first LED stack, an upper bonding layer disposed between the second LED stack and the third LED stack to couple the third LED stack to the second LED stack, and a first hydrophilic material layer disposed between the first LED stack and the upper bonding layer.
