Abstract: A head mount display device includes a display panel which displays image based on an image signal, a calculator which calculates an initial image luminance and a watching image luminance based on an equation “log(Lth)=c1 log(La)+c2 log(w)+c3, where Lth is a determination luminance, La is an adaptive environment luminance, w is an offset, c1 is a first constant, c2 is a second constant, and c3 is a third constant” that is a modelling for a relationship of an adaptive environment luminance in which eyes of a user are adapted and a determination luminance in which the eyes of the user do not recognize a discomfort, and a luminance controller which changes the initial image luminance of the image to the watching image luminance during an adaptive time.

Abstract: Provided is a display device including a display panel, a first backlight unit, and a second backlight unit. The first backlight unit provides first light beams to the display panel. The second backlight unit is disposed between the display panel and the first backlight unit, and provides second light beams which have a different wavelength from that of the first light beams to the display panel. The second backlight unit includes a front light guide plate and a short-wavelength light source. The short-wavelength light source emits light which has a wavelength of about 340 nm to about 430 nm to the top surface of the front light guide plate.
