Abstract
A display apparatus includes a backlight unit which emits a light, and a display panel which receives the light to display an image. The backlight unit includes a driving circuit which outputs a driving voltage and a reference voltage; and p light source blocks connected to the driving circuit, p being a natural number greater than or equal to 2, where each light source block of the p light source blocks receives the driving voltage through a first terminal thereof and the reference voltage through a second terminal thereof to generate the light, and the p light source blocks are divided into a plurality of groups, each group including at least two light source blocks. The driving circuit includes a first switching section which applies the driving voltage to first terminals of the p light source blocks, and a second switching section which applies the reference voltage to the second terminal of at least one of the p light source blocks.
