1. A display device, comprising:
a plurality of pixels connected to scan lines and data lines, wherein each of the pixels includes a driving transistor and at least one light emitting element; and
a timing controller configured to generate output data using external input data,
wherein the timing controller comprises:
a first compensator configured to generate first data by correcting the external input data using at least one of optical measurement information, a threshold voltage of each of the driving transistors, mobility information, dimming information, and temperature information; and
an afterimage compensator configured to generate second data by based on age information of each light emitting element and the first data, generate third data by based on a current amount corresponding to the first data and a current amount corresponding to the second data, and generate the age information by accumulating the third data.
