A display device and a position detecting method thereof are provided to detect the position of an object which comes in contact with or approaches a display surface of the display device, in high precision. A memory unit(45) stores default or detection data. An image generating unit produces an image for determination. An image determining unit determines whether an image of an object to be detected is included in the image for determination. If the image of the detected object is not included, the determining unit stores the image for determination as the default. In case the image of the detected object is included, the determining unit stores the image for determination as detection data. A location calculating unit calculates the position of the detected object based on images memorized as the detection data and default.
