Abstract
Disclosed is a display device including a base layer, a circuit layer including a plurality of transistors spaced apart from each other and disposed on a top of the base layer, a plurality of insulating layers disposed on a top of the base layer, and a plurality of contact electrodes electrically connected to the transistors, respectively, a first light emitting unit disposed on a top of the circuit layer, a second light emitting unit, and a lower protrusion disposed between at least one of the transistors and the second lower electrode, wherein at least one of the contact electrodes is disposed to extend to a top surface of the lower protrusion in the circuit layer while following a shape of the lower protrusion to simplify an etching process of an encapsulation layer.
