Abstract: A display device includes a substrate; a transistor disposed on the substrate; a first insulating layer disposed on the transistor; and a first pixel electrode and a second pixel electrode disposed on the first insulating layer to be adjacent to each other. The first insulating layer includes a first opening between the first pixel electrode and the second pixel electrode.

Abstract: Method for controlling a white balance in a plasma display panel device, is disclosed, including the steps of (1) displaying one frame of gradation on an entire screen of the plasma display panel device, (2) discharging and erasing all cells in the plasma display panel device, (3) addressing all R cells, G cells, or B cells of the entire cells at a time; and (4) providing additional sustain pulses having numbers different from one another to the R cells, G cells and B cells addressed in the step (3) to reduce luminance differences between the R cells, G cells and B cells, thereby providing additional sustain pulses with numbers different from one another in the order of R cell>G cell>B cell to R cells, G cells, B cells after display of one frame of gradation on an entire screen, resulting in significant reduction of luminance differences between the R cells, G cells, B cells caused by provision of identical gradation data thereto, whereby facilitating implementation of a stable white balance and exact c
