Abstract: An image display apparatus is disclosed. The image display according to an embodiment of the present disclosure includes a signal processing device including a first logic circuit to process a first voltage range of a voltage level of the input signal, a second logic circuit to process a second voltage range of the voltage level of the input signal, higher than the first voltage range, and a protection control circuit including a protection switch and a protection controller for controlling the protection switch, wherein the protection switch is turned on based on the protection controller being turned off or powered down. Accordingly, a breakdown phenomenon can be reduced in case of power off or power down.
