ABSTRACT:
A light emission device and a display device having the light emission device are provided. The light emission device includes first and second substrates that are arranged to face each other, an electron emission unit that is located on a first surface of the first substrate facing the second substrate and has electron emission regions and driving electrodes, a light emission unit that is located on a surface of the second substrate and has an anode electrode and one or more phosphor layers, and a surface heat generation unit that is located on a second surface (or outer surface) of the first substrate facing away from the second substrate to control a temperature of the first substrate using a resistive layer having a positive temperature coefficient (PTC) property.
