Abstract
A display device includes a display panel and an ion generator for generating positive ions and negative ions. The display device kills microorganisms or decomposes and removes harmful organic substances (e.g., sources of odor or environmental hormones), which exist either on the screen or in the air surrounding the display device, by utilizing the action of the positive and negative ions.
