Abstract: Provided are an eye-tracking device that may rapidly and accurately track an observer's eye and may be made compact, and a display apparatus including the eye-tracking device. The eye-tracking device includes: a light source configured to emit an illumination light; a light guide plate configured to transmit the illumination light emitted from the light source to an observer's eye and transmit the illumination light reflected from the observer's eye in a direction opposite to a propagation direction of the illumination light emitted from the light source; a photodetector array configured to detect the illumination light reflected from the observer's eye; and a signal processor configured to determine an angle of rotation of the observer's eye based on a two-dimensional (2D) intensity distribution of the illumination light detected by the photodetector array.
