The present invention provides a display device that can improve the detection sensitivity for detecting the approach of a user's face, hand, or the like. The display device 10 includes a display substrate D and a bezel 4 that covers side surfaces and a rear surface of the display substrate D. The bezel 4 includes a conductive section 4a and an insulating section 4b. The insulating section 4b covers the side surfaces and the rear surface of the display substrate D and has insulating properties. The conductive section 4a is provided on a surface of the insulating section 4b covering the side surfaces of the display substrate D and has conductivity. The conductive section 4a is configured such that a predetermined voltage is applied thereto and a capacitance is formed between the conductive section 4a and a dielectric object.
