ABSTRACT:
An aperture grill type display device is provided that displays a picture including two areas whose luminance values are different from each other without vertical stripes. The aperture grill type display device includes an aperture grill to which plural wires are attached. When displaying a picture including a window whose luminance value is higher than that of a desktop, the luminance value of the window is decreased if the energy that electron beams emitted from an electron gun of the display device give to the wires for displaying the window exceeds the energy that the electron beams give to all the wires by a predetermined ratio.
