Abstract
A method of manufacturing a display module includes preparing a first substrate structure including an light-emitting diode (LED) array containing a plurality of LED cells, electrode pads connected to the first and second conductivity-type semiconductor layers, and a first bonding layer covering the LED array; preparing a second substrate structure including a plurality of thin-film transistor (TFT) cells disposed on a second substrate, and each having a source region, a drain region and a gate electrode disposed therebetween, the second substrate structure being provided by forming a circuit region, in which connection portions disposed to correspond to the electrode pads are exposed to one surface thereof, and by forming a second bonding layer covering the circuit region, respectively planarizing the first and second bonding layers, and bonding the first and second substrate structures to each other.
