PROBLEM TO BE SOLVED: To provide a display device capable of suppressing the power consumption of each of light sources of a sidelight light source when controlling the brightness of each light source independently.SOLUTION: The display device comprises: an image display panel; a planar light source including a light guide plate, a first sidelight light source and a second sidelight light source; and a control section controlling the brightness of each light source independently. The control section divides the entire display surface of the image display panel into a first display surface and a second display surface, sets a brightness determination block in which the first display surface and the second display surface are respectively divided into plural pieces in a light source array direction in which the light sources are arrayed and in a light entrance direction perpendicular to the light source array direction. When an image is displayed according to information of an image input signal, the control section further determines a brightness determination block that has the highest brightness in the light entrance direction from the brightness determination blocks in the same position in the light source array direction, determines a block for brightness correction with reference to light source brightness information, and controls a light source lighting amount of each light source so as to achieve the brightness of the determined brightness determination block.SELECTED DRAWING: Figure 1 |
