The earliest galaxies are red shifted into the infrared spectrum that they are invisible in optical instruments.
Since the universe is permeated with a Cosmic Infrared Background (as opposed to the BB remnant Cosmic Microwave Background), detecting these galaxies with IR telescopes is extremely difficult.
It's analogous to the difficulties of imaging a very faint galaxy in a light polluted sky.
