Abstract: An image display device includes: a processor; a memory configured to store channel information corresponding to at least one channel; and at least one program which is stored in the memory and executed by the processor. The program may include instructions for controlling a display so as to move a channel indicator in a first or second direction on a channel scroll bar and to display channel information of a channel corresponding to a point at which the channel indicator is located, in response to a first input of pressing a channel-up or channel-down key for a long time, and for switching a current channel to the channel corresponding to the point at which the channel indicator is located and displaying an image corresponding to the switched channel, in response to a second input of releasing the channel-up or channel-down key.
