Display devices with image sensors are provided. Display pixel portions are disposed at intersections of gate lines and source lines and arranged as a matrix. Each display pixel portion includes a liquid crystal element, a photo detector detecting an incident light, a hold device sustaining an analog first data corresponding to a light flux of the incident light detected by the photo detector, and a data determination device generating a second data according to the first data sustained by the hold device. A gate driver selectively activates the gate lines. A source driver provides display data to the source lines. An output device retrieves the analyzed output data. The analyzed output data is the second data output by the data determination device through the source lines. A sensitivity control device changes a determination base of the analyzed output data corresponding to the intensity of the incident light.
