Abstract:
1. A display device comprising: an optical panel including an image display area; a backlight unit including a light guiding plate, which is disposed to be overlapped to the optical panel, and light sources which are arranged at a plurality of side surfaces of the light guiding plate; a first mode in which a first image and a second image which are divided based on the time or optically each other are displayed in the image display area; and a second mode which a third image is displayed without being divided based on the time or optically in the image display area, wherein the light sources include a first light emitting element row which disposed along a first side surface among the plurality of the side surfaces, a second light emitting element row which disposed along a second side surface which is different from the first side surface among the plurality of the side surfaces, a third light emitting element row which disposed along a third side surface facing the first side surface and a fourth light emitting element row which disposed along a fourth side surface facing the second side surface, and wherein a second average of light emitting intensity of the light sources in the second mode is lower than a first average of light emitting intensity of the light sources in the first mode by controlling at least the light emitting intensities of the second light emitting element row and the fourth light emitting element row.
