Display device

In one embodiment of the present invention, a display device is disclosed which performs a divided-screen active driving, and which allows (i) its emitting region to be divided into smaller units, irrespective of the smallest module unit of a light source; and (ii) minimizing increase in costs for a driving system and manufacturing of an area light source, a display device of the present invention includes: a display panel having unit display pixels; an area light source arranged on a back surface of the display panel, the area light source having an emitting region which is divided into divided emitting regions; and a controlling section for controlling luminance of each of the divided emitting regions of the area light source, based on luminance information of video signals input, wherein the area light source includes: unit emitting pixels which controls light emission of the divided emitting regions through a matrix driving; the unit emitting pixels each having an electron emitting element for emitting an electron, and a fluorescent substance which emits light by being excited by the electron emitted from the electron emitting element, the unit emitting pixels each occupying an area which is equivalent to an area of plural pixels out of the unit display pixels.
