Abstract
Provided are a liquid crystal display, a method of estimating ambient light, and a driving method of the liquid crystal display. The liquid crystal display includes a first electrode and a second electrode generating an electric field, liquid crystal molecules the orientation state of which is changed by the generated electric field, and a photodetector sensing the light passing through the liquid crystal molecules.
