The present disclosure relates to an artificial intelligence (AI) system and application thereof, the system simulating functions, such as recognition and judgment, of a human brain by utilizing a machine learning algorithm such as deep learning. An image display device according to an embodiment includes a display, a memory for storing one or more instructions, and a processor for executing the one or more instructions stored in the memory, wherein the processor can: determine whether it is a recommended time for outputting advertisement content from a user's log data on the basis of a first learning model using one or more neural networks by executing the one or more instructions; if it is determined to be the recommended time for outputting the advertisement content, determine a recommended attribute of an advertisement display area from the user's log data on the basis of a second learning model using the one or more neural networks; adjust the attribute of the advertisement display area on the basis of the determined recommended attribute; and control the display to output the advertisement content in the advertisement display area of which the attribute has been adjusted.
